BACKGROUND Technological FieldThe disclosed embodiments generally relate to systems and methods for dataset management. More particularly, the disclosed embodiments relate to systems and methods for controlling access in a dataset management system using quotas.
Background InformationComputerized devices are now prevalent, and data produced and maintained by those devices is increasing.
Audio sensors are now part of numerous devices, and the availability of audio data produced by those devices is increasing.
Image sensors are now part of numerous devices, from security systems to mobile phones, and the availability of images and videos produced by those devices is increasing.
Machine learning algorithms, that use data to generate insights, rules and algorithms, are widely used.
SUMMARYIn some embodiments, systems and methods for the creation, maintenance, and usage of datasets and annotations are provided.
In some embodiments, examples may be used selectively. For example, information associated with external devices may be obtained, weights may be assigned to examples using the obtained information, and inference models may be generated using the assignment of weights. In some examples, update information associated with the external devices may be obtained, the assignment of weights may be updated using the update information, and updated inference models may be generated using the updated assignment of weights.
In some embodiments, actions may be triggered automatically in a dataset management system. For example, a change to data maintained by the dataset management system may be detected, and a rule associated with the data and with an action may be obtained. Further, it may be determined if the change is a trigger according to the rule. In some examples, when the change is determined to be a trigger according to the rule, the action associated with the rule may be performed, for example with the data associated with the change. In some examples, when the change is determined not to be a trigger according to the rule, the system may forgo the performance of the action, for example for the data associated with the change.
In some embodiments, inference models may be employed based on available processing resources. For example, available processing resources information may be received, inference model may be selected (for example, based on the received information), and the selected inference model may be utilized. In some cases, an update to the available processing resources information may be received, the selected inference model may be updated (for example, based on the received update), and the updated inference model may be utilized.
In some embodiments, personalized quality assurance of inference models may be performed. For example, data items associated with a group of devices may be obtained, results of applying the data items to inference models may be obtained, the results of applying the data items to a first inference model may be compared with the results of applying the data items to a second inference model, and the compatibility of the second inference model to the group of devices may be assessed, for example based on the comparison results. In some examples, when the second inference model is found compatible, the second inference model may be utilized in tasks associated with the group of devices. In some examples, when the second inference model is found incompatible, the system may forgo the usage of the second inference model in one or more tasks associated with the group of devices.
In some embodiments, descriptors of artificial neural networks may be generated and/or used. For example, an artificial neural network may be obtained, the artificial neural network may be obtained, descriptors of the segments may be calculated, and a descriptor of the artificial neural network may be compiled. In some examples, a match score for a pair of artificial neural networks may be calculated (for example using the descriptors compiled for the two artificial neural networks), and actions may be selected based on the matching score.
In some embodiments, required processing resources for machine learning tasks may be estimated. For example, properties of a machine learning training task may be obtained, properties of external devices may be obtained, and the processing resources requirements of the machine learning training task may be estimated (for example using the properties of the external devices). In some examples, the estimation may be provided to a user. In some examples, a group of devices may be selected, and the selected group of devices may be triggered to perform the machine learning training task.
In some embodiments, datasets may be enriched while learning. For example, intermediate results of training machine learning algorithms may be obtained. Additional training examples may be selected based on the intermediate results. In some cases, synthetic examples may be generated based on the intermediate results. The machine learning algorithms may be further trained using the selected additional training examples and/or the generated synthetic examples.
In some embodiments, datasets may be incrementally annotated. For example, a group of labeled examples and a group of unlabeled examples may be obtained, a first inference model may be generated using the group of labeled examples, labels may be assigned to at least part of the group of unlabeled examples using the first inference model, confidence levels may be assigned to the assigned labels, a subset of the group of unlabeled examples may be selected using the confidence levels, and in some cases a second inference model may be generated using the selected subset and/or the corresponding assigned labels.
In some embodiments, annotations of datasets may be merged. For example, assignments of labels to data-points may be obtained, confidence levels associated with the assignments of labels may be obtained. Further, the assignments of labels may be merged, for example based on the confidence levels. In some cases, inference models may be generated using the merged assignment of labels. In some examples, an update to the assignments of labels to data-points and/or the confidence levels may be obtained, and the merged assignment of labels may be updated.
In some embodiments, access to a dataset management system may be controlled using permission records. For example, a request to access information in a dataset management system may be obtained from an entity, and a permission record associated with the entity may be selected. Further, it may be determined if the entity has permission to access the information. In some examples, when the entity has permission to access the information, the access to the information may be allowed. In some examples, when the entity has no permission to access the information, the access to the information may be denied.
In some embodiments, access to a dataset management system may be controlled using quotas. For example, a request to perform an action in a dataset management system may be obtained from an entity, and a quota record associated with the entity may be selected. Further, it may be determined if the entity has sufficient quota to perform the action. In some examples, when the entity has sufficient quota to perform the action, the request may be allowed. In some examples, when the entity has insufficient quota to perform the action, the request may be denied.
In some embodiments, a project schedule may be maintained in a dataset management system. For example, a progress update and a project schedule record may be obtained. The project schedule record may be updated, for example according to the progress update. In some examples, a delay may be predicted, and a corresponding indication may be provided.

For example, observing a dataset and/or an annotation with some distribution of elements may cause the algorithm to create a view containing a sample of the elements with a different distribution. Furthermore, detecting a change of the dataset and/or annotation that caused a change of said distribution may lead the algorithm to modify the view to match the change. Furthermore, when changes to the dataset and/or the annotation cause the said distribution to reach a certain desired property, the algorithm may remove the view.

In some examples, the synthetic examples (alone or in combination with the plurality of examples and/or the corresponding assigned weights) may be split into at least two of a training set and/or a validation set and/or a test set. In some examples, a machine learning algorithm may be trained using the synthetic examples (alone or in combination with the plurality of examples and/or the corresponding assigned weights) to generate an inference model.

In some embodiments, updating the assignment of weights using the update information (Step 750) may comprise updating the assignment of weights to examples of Step 720 according to the update information obtained by Step 740. For example, Step 720 may be used with the updated information associated with the external devices obtained by Step 740 to generate an updated assignment of weights. In some examples, Step 750 may compare the updated information associated with the external devices obtained by Step 740 with the original information associated with the external devices obtained by Step 710 to determine if the magnitude of the update is above a selected threshold. Further, in response to a magnitude of update that is above the selected threshold, Step 750 may update the assignment of weights to examples, and in response to a magnitude of update that is below the selected threshold, Step 750 may forgo updating the assignment of weights to examples (and in some cases, process 700 may forgo Step 760, may return to Step 740, may stop, and so forth).

In some examples, Step 760 may compare the updated assignment of weights to examples obtained by Step 750 with the original assignment of weights to examples obtained by Step 720 to determine if the magnitude of the update is above a selected threshold. Further, in response to a magnitude of update that is above the selected threshold, Step 760 may generate the updated inference models, and in response to a magnitude of update that is below the selected threshold, Step 760 may forgo generating the updated inference models. In some examples, the inference model generated by Step 760 may be utilized, for example using Step 930, using Step 1050, and so forth.

In some examples, Step 810 may monitor datasets 610 and/or annotations 620 and/or views 630 (for example, in a poll scheme, in a push scheme, etc.) to detect changes to data maintained by a dataset management system. In some examples, Step 810 may be repeated to detect a plurality of changes.
In some embodiments, obtaining a rule associated with the data and with an action (Step 820) may comprise accessing rules associated with the data changed (for example, as detected by Step 810) and/or with the change detected by Step 810 and/or with one or more actions. In some examples, the rule may be configured to classify a change to the data (for example, the change detected by Step 810) as a change that is a trigger according to the rule or a change that is not a trigger according to the rule. In some examples, at least part of the rule may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the rule may be received from external devices (for example, from the devices associated with the data and/or with the actions), for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In yet another example, the rule may be selected of a plurality of alternative rules, for example based on the data changed and/or the change detected by Step 810 and/or the entities that caused the detected change. In some examples, at least part of the rule may be preprogrammed manually. In another example, at least part of the rule may be the result of training a machine learning algorithm and/or a deep learning algorithm using training examples. The training examples may include examples of changes together with a corresponding desired classification as a trigger or not as a trigger. In yet another example, the rule may be based on, at least in part, on the output of one or more artificial neural networks. In some examples, Step 820 may be repeated to obtain a plurality of rules.
In some embodiments, determining if the change is a trigger according to the rule (Step 830) may comprise determining if the change detected by Step 810 is a trigger according to the rule obtained by Step 820. For example, the rule may be configured to classify a change as a change that is a trigger according to the rule or a change that is not a trigger according to the rule, and the determination may be based on the classification of the change by the rule. In some examples, Step 830 may be repeated for a one or more changes and/or one or more rules. For example, Step 830 may determine if a first change detected by Step 810 is a trigger according to a first rule obtained by Step 820, determine if the first change detected by Step 810 is a trigger according to a second rule obtained by Step 820, determine if the first change detected by Step 810 is a trigger according to a third rule obtained by Step 820, determine if a second change detected by Step 810 is a trigger according to the first rule obtained by Step 820, determine if a third change detected by Step 810 is a trigger according to the first rule obtained by Step 820, and so forth.
In some examples, properties of the detected change may comprise a number of data-points added to selected datasets (denoted d1), and/or number of data-points removed from selected datasets (denoted d2), and/or number of data-points modified in selected datasets (denoted d3), and/or number of elements (such as labels, tags, desired outputs, etc.) added to selected annotations (denoted d4), and/or number of elements (such as labels, tags, desired outputs, etc.) removed from selected annotations (denoted d5), and/or number of elements (such as labels, tags, desired outputs, etc.) modified in selected annotations (denoted d6), and so forth. Further, the rule may classify the change according to a value of a function f( ) of d1 and/or d2 and/or d3 and/or d4 and/or d5 and/or d6 and/or other inputs. For example, the output of the function f( ) for the change detected by Step 810 may be compared with a selected threshold, and the detected change may be classified as a change that is a trigger or not a trigger according to the comparison result. Some examples for such function f( ) may include, f( )=d1, f( )=d2, f( )=d3, f(d1, d2, d3, d4, d5, d6)=d4, f( )=d5, f( )=d6, f( )=max(d1, d2, d3), f( )=max(d1, d2), f( )=max(d1, d2)+d3, f( )=max(d4, d5, d6), f( )=max(d4, d5), f( )=max(d4, d5)+d6, f( )=max(d1, d2, d3, d4, d5, d6), f( )=max(d1, d2, d4, d5), any combination of the above (for example, a linear combination of the above, a non-linear combination of the above, a maximum value of at least some of the above, etc.), and so forth. For example, for the function f( )=d1 the selected threshold may comprise a minimal number of data-points added to the selected datasets, for the function f( )=d2 the selected threshold may comprise a minimal number of data-points removed from the selected datasets, for the function f( )=d3 the selected threshold may comprise a minimal number of data-points modified in the selected datasets, for the function f( )=d4 the selected threshold may comprise a minimal number of elements (such as labels, tags, desired outputs, etc.) added to the selected annotations, for the function f( )=d5 the selected threshold may comprise a minimal number of elements (such as labels, tags, desired outputs, etc.) removed from the selected annotations, for the function f( )=d6 the selected threshold may comprise a minimal number of elements (such as labels, tags, desired outputs, etc.) modified in the selected annotations, and so forth. In some examples, the data changed after the change and/or the change detected may be associated with a plurality of annotations, and the rule may specifies a family of distributions of annotations for which the change is classified as a trigger. For example, the changed data may be associated with a plurality of annotations included in the data, the detected change may be associated with annotations added and/or deleted and/or modified by the change, and so forth. In some examples, a measure of the distribution may be calculated and compared with a threshold to determine the classification of the distribution. Some examples of such measure may include entropy, Tsallis entropy, dispersion, statistical distance (such as f-divergence, Kullback-Leibler divergence, Hellinger distance, Total variation distance, Rényi's divergence, Jensen-Shannon divergence, Lévy-Prokhorov metric, Bhattacharyya distance, Kantorovich metric, Tsallis divergence, etc.) to a selected distribution, and so forth.
In some examples, when the change detected by Step 810 is determined by Step 830 to be a trigger according to the rule, the flow of process 800 may continue to perform the action (Step 840). In some examples, when the change detected by Step 810 is determined by Step 830 not to be a trigger according to the rule, the flow of process 800 may continue to forgo performing the action (Step 850). For example, Step 830 may determine that a first change detected by Step 810 is a trigger according to a first rule obtained by Step 820, a second change detected by Step 810 is not a trigger according to the first rule, the first and second changes are triggers according to a second rule obtained by Step 820, the first and second changes are not triggers according to a third rule obtained by Step 820, and so forth. As a result, process 800 may perform a first action associated with the first rule with data associated with the first change (using Step 840), may forgo performing the first action with data associated with the second change (using Step 850), may perform a second action associated with the second rule with data associated with the first change and with data associated with the second change (using Step 840), may forgo performing a third action associated with the third rule with data associated with the first change and with data associated with the second change (using Step 850), and so forth. In some examples, process 800 may determine that the time elapsed since a previous performance of an action (for example, an action associated with a rule) is below a selected threshold, and withhold and/or forgo performing the action (for example, even when the change detected by Step 810 is determined by Step 830 to be a trigger according to the rule), for example using Step 850.
In some embodiments, performing the action (Step 840) may comprise performing the action associated with the rule obtained by Step 820, for example using data associated with the change detected by Step 810. In some examples, the action may comprise providing a notification, for example to a user, to a system manager, to another process, to an external device, to an entity associated with the data changed (for example, owner of the data, creator of the data, contributor to the data, user of the data, etc.), and so forth. For example, the notification may be provided visually (for example, using a graphical user interface, using a web site, using a display system, using an augmented reality system, using a virtual reality system, in a printed form, etc.), audibly (for example, using audio speakers, using headset, etc.), and so forth. In another example, the notification may be transmitted to an external device (for example, using communication devices, over network 130, etc.), provided to another process (for example, through a memory module), and so forth. In some examples, the notification may comprise information related to the changed data, such as description of the changed data, description of the change to the data, an amount associated with the change (for example, number of elements modified and/or created and/or deleted), a time associated with the change (for example, time of the change, time elapsed since last change, etc.), and so forth. In some examples, the notification may comprise a suggestion to train a machine learning algorithm, for example with data associated with the change (such as datasets and/or annotations added and/or modified). In some examples, the notification may comprise a suggestion to merge two or more annotations. For example, annotations that were added and/or modified may be compared with previous annotations (for example, previous annotations associated with the same dataset as the added and/or modified annotations), and a suggestion to merge the added and/or modified annotations with the previous annotations may be provided when the comparison result indicates that the change is above a selected threshold, is below a selected threshold, and so forth. In some examples, annotations that were added and/or modified may be compared with previous annotations (for example, previous annotations associated with the same dataset as the added and/or modified annotations), and the added and/or modified annotations may be merged with the previous annotations when the comparison result indicates that the change is above a selected threshold, is below a selected threshold, and so forth.
In some examples, the action may comprise executing selected automated processes, such as one or more of processes 700, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700 and 1800. For example, the detected change may comprise a change to an inference model in algorithms 640 and/or an addition of a new inference model to algorithms 640, and process 1000 may be used to compare the changed inference model and/or the new inference model with previous ones. For example, the detected change may comprise a change to an artificial neural network in algorithms 640 and/or an addition of a new artificial neural network to algorithms 640, and process 1100 may be used to compare the changed and/or new artificial neural network with previous ones.

In some examples, an inference model may be selected out of a plurality of alternative inference models based on the available processing resources, for example using a lookup-table, using a selection rule, and so forth. For example, minimal processing resources requirements may be specified for different inference models, and inference models with minimal processing resources requirements that exceed the available processing resources may be rejected. In another example, process 900 may not have permission to use some inference models (for example, as determined using process 1600), and these inference models may be rejected. In yet another example, process 900 may not have sufficient quota to use some inference models (for example, as determined using process 1700), and these inference models may be rejected. Further, out of the inference models that are not rejected, the inference model with the most desired characteristics may be selected (for example, the inference model with best performances, the inference model that can handle the largest number of classes, the inference model with the highest score, and so forth).
In some examples, the performances of inference models when utilized using the available processing resources may be estimated, and the inference model with the best estimated performances may be selected according to some rules. For example, the estimated performances may include estimated running time for a selected input examples, inference models with estimated running time that exceeds some selected threshold may be rejected from the selection of the inference model, and an inference model with the best estimated performances according to some criteria may be selected out of the non-rejected inference models.

In some examples, at least one rule may be used to generate a new inference model and/or to modify at least one aspect of an existing inference model according to the available processing resources information. For example, the inference model may comprise an ensemble model (where a plurality of internal inference models are used, and the final result produced by the inference model is based on a function of the plurality of results obtained from the internal inference models), and the at least one rule may select the number of inference models in the ensemble and/or the types of the internal inference models according to the available processing resources information.

For example, a set of training examples to be used by a k-nearest-neighbors algorithm may be sampled out of a group of alternative learning examples, and the number of samples in the set may be selected according to the available memory size. In some examples, training examples may be sampled (for example, according to the available processing resources information, to available memory size, etc.), weights may be assigned to the sampled training examples according to properties of devices associated with the available processing resources information, for example using process 700, which may further use the weights together with the training examples to generate the inference model. In some examples, the inference model may be generated by training a machine learning algorithm using a plurality of training examples (for example by using training data from datasets 610 and/or annotations 620 and/or views 630), and hyper-parameters of the machine learning algorithm may be selected based on the available processing resources information. For example, the number of artificial neurons in an artificial neural network may be selected according to the available memory size, according to the number of available processing cores, according to the number of instructions per a time unit the available processing units may perform, according to the available bus speed, and so forth.

In some embodiments, the available processing resources information may comprise a number of artificial neurons evaluations in a time unit, and an inference model that comprises an artificial neural network that can be evaluated in selected time duration may be selected. For example, if the available processing resources information indicates that the processing devices can evaluate m1 artificial neurons per second, ant the selected time duration is t1 seconds, an artificial neural network that comprises m1*t1−c artificial neurons or less for a selected non-negative constant c may be selected. For example, m1 may be ten million, t1 may be ten milliseconds, c may be zero, and an artificial neural network that comprises one hundred thousand artificial neurons may be selected. In some examples, the available processing resources information may comprise a distribution of number of artificial neurons evaluations in a time unit (for example, a distribution of measured number of artificial neurons evaluations in a time unit), and an artificial neural network that can be evaluated within selected time duration in a selected portion of the cases according to the distribution may be selected.

For example, the message may comprise at least part of the inference models. In another example, the message may comprise an indication of the inference models to be utilized. In some examples, a similar message may be provided to another process (for example through a memory module, such as memory units 210, shared memory modules 410, etc.), and the message may be configured to cause the other process to utilize the inference models as described above. In some examples, utilizing the selected inference model may comprise updating a project schedule record, for example by adding a task to utilize the selected inference model.

For example, information specifying parts of a desired inference model may be received by the external devices (for example, information specifying parts selected by Step 920 may be provided and/or transmitted by Step 930), and the desired inference model may be assembled from the specified parts (for example, where the parts are obtained from algorithms 640).
In some examples, generating the selected at least one inference model may comprise training a machine learning algorithm using training examples to obtain at least part of the selected at least one inference model. For example, a machine learning algorithm may be trained (for example by algorithms 640) using training examples (for example by using training data from datasets 610 and/or annotations 620 and/or views 630), for example using training examples selected by Step 930 according to selection of Step 920. In some examples, the training examples may be selected from a plurality of alternative training examples (for example from datasets 610 and/or annotations 620 and/or views 630) according to selections of Step 920. For example, the training examples may be selected according to their size and according to rules chosen by Step 920 in response to the available processing resources information obtained by Step 910. Some examples of such rules may include the selection of training examples with size that is below a selected threshold, above a selected threshold, and so forth.
In some embodiments, obtaining an update to the available processing resources information (Step 940) may comprise obtaining an update to the information received by Step 910. For example, Step 940 may use Step 910 to obtain new available processing resources information which may be an update of the available processing resources information of Step 910. In another example, modified parts of the available processing resources information may be obtained. For example, at least part of the modified parts may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the modified parts may be received from external devices (for example, from the device configured to utilize inference models), for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In some examples, at least part of the modified parts may be generated, for example by using a processing resources measuring software program. For example, the processing resources measuring software program may monitor a device and report to Step 940 when the available processing resources changes and/or when the change to the available processing resources is greater than a selected threshold. In another example, the update to the available processing resources information may comprise an update to a list of available devices (such as addition of devices, removal of devices, and so forth). In yet another example, the number of artificial neurons evaluations in a time unit and/or the distribution of the number of artificial neurons evaluations in a time unit may be updated, for example based on actual usage data of the inference model selected by Step 920.
In some examples, Step 940 may analyze the update to the available processing resources information (for example, by analyzing the obtained update, by comparing the available processing resources information of Step 910 to the updated available processing resources information, etc.) to determine if the update to the information related to available processing resources is below a selected threshold. For example, the available processing resources may comprise a numerical value and/or an amount (such as available memory size, speed, bandwidth, latency, throughput, processor clock speed, number of available processing cores, number of instructions per second, number of artificial neurons evaluations per second, etc.), and Step 940 may determine if the change to the numerical value and/or the amount is below a selected threshold. In some examples, when Step 940 determines that the update is below the selected threshold, process 900 may withhold and/or forgo Step 950 and/or Step 960.
In some embodiments, updating the selected inference model (Step 950) may comprise updating at least one selection of inference models (such as the selection of inference model of Step 920) based on the update to the information related to available processing resources (for example as received by Step 940) to obtain at least one updated selection of inference model. In some examples, Step 950 may use Step 920 with the updated information related to available processing resources to select and/or generate new inference models which are updates to the original selection of inference models of Step 920. In some examples, an update to at least part of the inference model may be selected of a plurality of alternative updates based on the update to the information related to available processing resources (for example, in a similar fashion to Step 920). In some examples, an update to at least part of the inference model may be generated (for example, using rules and/or training examples in a similar fashion to Step 920). For example, the inference model selected by Step 920 may comprise a result of training a machine learning algorithm on a plurality of selected training examples, and Step 940 may update the selected plurality according to the update to the information related to available processing resources (for example, the amount of training examples may be increased and/or decreased in response to an update to the available memory size). Further, the training of the machine learning algorithm may be updated according to the updated plurality of selected training examples. In another example, at least one hyper-parameter of the machine learning algorithm used to generate the inference model may be updated (for example, a batch size may be updated in response to an update of available cache memory size, a sampling rate may be changed in response to change of available memory size, and so forth). In some examples, Step 950 may compare the updated inference model with the inference model of Step 920 to determine if the update to the inference model is below a selected threshold (for example, using process 1000, using process 1100, etc.). In some examples, when Step 950 determines that the update is below the selected threshold, process 900 may withhold and/or forgo Step 960.
In some embodiments, utilizing the updated inference model (Step 960) may comprise causing the at least one device (such as the devices associated with the available processing resources information received by Step 910 and/or the devices associated with the update obtained by Step 940) to utilize at least one updated inference model (such as the updated inference of Step 950). For example, Step 960 may use Step 930 to cause the devices to utilize the at least one updated inference model.
In some embodiments, information related to available processing resources associated with at least one device may be generated, for example by the at least one device, for example by using a processing resources measuring software program. The generated information may be provided to process 900, for example by transmitting the generated information to an external device that performs process 900, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, etc.), by writing the generated information to memory (such as memory units 210, shared memory modules 410, etc.), and so forth. In response, the at least one device may receive from process 900 an indication of an inference model (as described above), for example an indication of an inference model selected based on the generated information by Step 920 as described above. For example, the indication may be received as a message (for example using communication devices, such as communication modules 230, internal communication modules 440, external communication modules 450, etc.), by reading the indication of the inference model from memory (such as memory units 210, shared memory modules 410, etc.), and so forth.

For example, synthetic data items may be generated according to information about the group of devices, about the environment the group of devices function within, about data captured and/or processed by the group of devices, according to information obtained by Step 710, and so forth. In another example, some existing data items may be combined together to create more data items, for example using the Synthetic Minority Over-sampling Technique (SMOTE).

For example, Step 1030 may compare the results of applying a group of data items to a first inference model and a second inference model, where the first inference model is a result of training a machine learning algorithm using a plurality of training examples, and the second inference model is a result of training a machine learning algorithm (which may be the same or different from the first machine learning algorithm) using an update to the plurality of training examples.
In some examples, the first inference model and the second inference model of Step 1030 may be obtained from process 700 (for example, using the inference model generated by Step 730 as the first inference model, and the inference model generated by Step 760 as the second inference model), from process 1300 (for example, using the inference model generated by Step 1310 as the first inference model and the inference model generated by Step 1330 as the second inference model), from process 1400 (for example, obtaining the first inference model from Step 1420 and the second inference model from Step 1460), from process 1500 as described below, and so forth.
In some embodiments, assessing the compatibility of the second inference model (Step 1040) may comprise assessing the compatibility of the second inference model to the group of data items and/or to a group of devices associated with the group of data items based on a comparison performed by Step 1030, for example the comparison of the results of applying the group of data items (which in some cases may be associated with the group of devices) to a first inference model with the results of applying the group of data items to the second inference model. In some examples, Step 1040 may be repeated for different groups of data items, which may be associated with different groups of devices. For example, Step 1040 may assess an inference model using a first comparison based on a first group of data items (which may be associated with a first group of devices), using a second comparison based on a second group of data items (which may be associated with a second group of devices), using a third comparison based on a third group of data items (which may be associated with a third group of devices), and so forth. In some examples, Step 1040 may assess the compatibility of the second inference model with respect to the first inference model used by Step 1030. For example, the second inference model may be assessed as better, equivalent, or worse in comparison to the first inference model. In some examples, Step 1040 may assign a score to the second inference model, such as a numerical score (for example, a score from zero to ten). For example, taking a score of the first inference model as a baseline, and based on the comparison of the results of the first inference model and the second inference model, a score for the second inference model may be calculated, for example as a function of the baseline score and the comparison result. In some examples, Step 1040 may assess the compatibility of the second inference model, to the group of data items and/or to the group of devices associated with the group of data items, as compatible or as incompatible. For example, a function may be used to convert the comparison results to compatible or incompatible assessment. The function may use a threshold to decide which comparison results are considered compatible and which are considered incompatible.
In some examples, when the second inference model is found compatible by Step 1040, the flow of process 1000 may continue to utilize the second inference model (Step 1050). In some examples, when the second inference model is found incompatible by Step 1040, the flow of process 1000 may continue to forgo the usage of the second inference model (Step 1060). For example, Step 1040 may assess the second inference model as compatible with a first group of data items and/or a first group of devices, and as incompatible with a second group of data items and/or a second group of devices. As a result, process 1000 may utilize the second inference model for tasks associated with the first group of data items and/or with the first group of devices (for example using Step 1050), and may forgo the usage of the second inference model for tasks associated with the second group of data items and/or the second group of devices (for example using Step 1060).
In some embodiments, utilizing the second inference model (Step 1050) may comprise utilizing the second inference model assessed by Step 1040 in tasks associated with the group of data items and/or with a group of devices associated with the group of data items. In some examples, Step 1050 may be repeated for different inference models and/or for different groups of data items and/or different groups of devices. For example, Step 1050 may utilize one inference model in a first group of tasks associated with a first group of data items and/or a first group of devices, utilize the one inference model in a second group of tasks associated with a second group of data items and/or a second group of devices, utilize another inference model in a third group of tasks associated with the first group of data items and/or the first group of devices, and so forth. In some examples, a message may be transmitted to the group of devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, etc.), and the message may be configured to cause the group of devices to utilize the second inference model. For example, the message may comprise at least part of the second inference model. In another example, the message may comprise an indication of the second inference model. In yet another example, the message may be further configured to cause the group of devices to delete at least part of another inference model (such as the first inference model of the comparison of Step 1030). In some examples, a message may be provided to another process (for example through a memory module, such as memory units 210, shared memory modules 410, etc.), and the message may be configured to cause the other process to utilize the second inference model and/or to delete other inference models (in a similar fashion to what described above).
In some examples, utilizing the second inference model may comprise applying input data associated with the group of data items to the second inference model to obtain at least one inferred value. For example, the input data may comprise information captured using at least one sensor, such as audio captured using audio sensors 250, images captured using image sensors 260, motion information captured using motion sensors 270, positioning information captured using positioning sensors 275, atmospheric pressure information captured using barometers, pressure information captured using pressure sensors, proximity information captured using proximity sensors, electrical impedance information captured using electrical impedance sensors, electrical voltage information captured using electrical voltage sensors, electrical current information captured using electrical current sensors, user input obtained using user input devices, and so forth.
In some embodiments, forgoing the usage of the second inference model (Step 1060) may comprise avoiding at least part of the usages of the second inference model in tasks associated with the group of data items and/or to a group of devices associated with the group of data items. In some examples, Step 1060 may be repeated for different inference models and/or for different groups of data items and/or different groups of devices. For example, Step 1060 may avoid at least part of the usages of one inference model in tasks associated with a first group of data items and/or a first group of devices, may avoid at least part of the usages of the one inference model in other tasks associated with a second group of data items and/or a second group of devices, may avoid at least part of the usages of another inference model in other tasks associated with the first group of data items and/or the first group of devices, and so forth. In some examples, Step 1060 may further comprise deleting at least part of an inference model (such as the second inference model). In some examples, a message may be transmitted to the group of devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, etc.), and the message may be configured to cause the group of devices to avoid at least part of the usages of the second inference model and/or to delete at least part of the second inference model. In some examples, a message may be provided to another process (for example through a memory module, such as memory units 210, shared memory modules 410, etc.), and the message may be configured to cause the other process to avoid at least part of the usages of the second inference model and/or to delete at least part of the second inference model.
In some embodiments, obtaining an artificial neural network (Step 1110) may comprise obtaining information defining at least part of the artificial neural network, such as the arrangement of the artificial neurons in a network and/or information about the artificial neurons. In some examples, the artificial neurons may be arranged as a directional graph and/or hypergraph, where each node of the graph and/or hypergraph may correspond to an artificial neuron, and the directional edges and/or hyperedges may define the flow of information among the artificial neurons. In some examples, an artificial neuron may be described as a function that converts inputs into outputs. For example, such function may include parameters, where in some cases the parameters may define the function, and therefore an artificial neuron may be described as a function together with the function parameters. In another example, the function may include a non-linear part that operates on a linear combination of the inputs, where the weights of the linear combination are part of the function parameters, and where the non-linear part may also depend on one or more parameters. Some examples of such non-linear parts may include step functions (where the thresholds and values may depend on parameters), sigmoid, tan h, ReLu, leaky ReLu, PReLU, randomized Leaky ReLu, softmax, maxout, any combination of the above, and so forth.
Some examples of possible types of artificial neural networks may include feedforward neural network, recursive neural network, multilayer perceptron, radial basis function neural network, self-organizing neural network (such as Kohonen self-organizing neural network), recurrent neural network, long-short term memory neural network, convolutional neural network, modular neural network, sequence-to-sequence neural network, deep neural network, shallow neural network, and so forth. In some examples, an artificial neural network may be programmed manually. In other examples, an artificial neural network may comprise an output of a machine learning algorithm (and in some cases, deep learning algorithm) trained using training examples. In such case, some of the parameters of the artificial neural network may be set manually and are called hyper-parameters, while the other parameters are set by the machine learning algorithm according to the training examples. In some examples, parameters and/or hyper-parameters of the artificial neural network may be obtained by Step 1110. In some examples, the machine learning algorithm used to train the artificial neural network may also have some hyper-parameters, such as optimizer, loss function, weight decay function, learning rate, dropout, stopping condition, number of epochs, batch size, momentum, random seed, and so forth. In some cases, at least part of the hyper-parameters of the machine learning algorithm may also be obtained by Step 1110.
In some examples, at least part of the information defining the artificial neural network may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the information defining the artificial neural network may be received from external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In some examples, at least part of the information defining the artificial neural network may be obtained by training the artificial neural network using training examples, for example using a backpropagation algorithm, using stochastic gradient descent algorithm, using any deep learning training algorithm, and so forth. In some examples, at least part of the information defining the artificial neural network may be obtained from algorithms 640 and/or tasks 650. In some examples, the obtained artificial neural network may be an output of another process (such as process 700, process 900, process 1200, process 1300, process 1400, process 1500, and so forth).
In some embodiments, segmenting the artificial neural network (Step 1120) may comprise analyzing an artificial neural network (such as the artificial neural network obtained by Step 1110) to obtain a plurality of segments of the artificial neural network. In some examples, a segment may be defined by the artificial neurons included in the segment. In some examples, a segment may comprise at least one artificial neuron, at least two artificial neurons, at least ten artificial neurons, at least one layer of the artificial neural network, at least one per mill of the network's artificial neurons, at least one percent of the network's artificial neurons, at least ten percent of the network's artificial neurons, and so forth. In some examples, a segment may comprise at most half of the network's artificial neurons, at most ten percent of the network's artificial neurons, at most one percent of the network's artificial neurons, and so forth. In some examples, the segments may be mutually exclusive, while in other examples the segments may have one or more artificial neurons in common.
In some examples, the artificial neural network may be segmented using graph segmentation algorithm and/or hypergraph segmentation algorithm, such as graph and/or hypergraph cut algorithms. In some examples, an affinity matrix and/or affinity tensor may be constructed, for example based on similarities among artificial neurons based on distance between the artificial neurons within the network. Such similarities may be based on the similarities among the functions of the artificial neurons, the parameters and/or hyper-parameters of the artificial neurons, the layers of the artificial neurons, the graph and/or hypergraph distance between the artificial neurons, and so forth. Using the affinity matrix and/or affinity tensor, affinity based clustering algorithms (such as spectral clustering and its many extensions) may be used to extract segments of the artificial neural network. Additionally or alternatively, algorithms like kernel PCA may use the affinity matrix to embed the artificial neurons in a mathematical space, following by clustering algorithms that may use the embedding to cluster the artificial neurons.
In some embodiments, calculating descriptors of the segments (Step 1130) may comprise calculating descriptors of segments of an artificial neural network (such as the segments obtained by Step 1120 of the artificial neural network obtained by Step 1110), for example by using values associated with the one or more artificial neurons of a segment to calculate the descriptor of the segment. In some examples, the values associated with the one or more artificial neurons may comprise values based on the outputs of the artificial neurons for a selected group of inputs. For example, the selected inputs may be fed through the artificial neural network, and the values may be based on the outputs of the artificial neurons in the artificial neural network. In another example, the selected inputs may be fed directly to the artificial neurons, and the values may be based on the outputs of the artificial neurons. Some examples of the values associated with the artificial neuron may comprise some selected outputs, values describing the distribution of the outputs, a curve fitted to the mapping of inputs to outputs, a histogram of the outputs, and so forth. In some examples, the values associated with the one or more artificial neurons may comprise values based on parameters and/or hyper-parameters of the artificial neurons, such as selected parameters and/or hyper-parameters, a function of some parameters and/or hyper-parameters, and so forth.
In some examples, at least part of the values associated with the artificial neurons of a segment may be combined to generate the descriptor of the segment. For example, at least part of the values associated with the artificial neurons of a segment may be aggregated into a mathematical set of values, and the mathematical set may be used as at least part of the descriptor of the segment. In another example, an average or a weighted average of at least part of the values associated with the artificial neurons of a segment may be calculated, optionally according to weights assigned to the artificial neurons of the segment, and the calculated average and/or weighted average may be used as at least part of the descriptor of the segment. In another example, properties of the distribution of at least part of the values associated with the artificial neurons of a segment may be used as at least part of the descriptor of the segment. Some examples of such properties may include mean, mode, median, standard deviation, variance, and so forth. In yet another example, a histogram of at least part of the values associated with the artificial neurons of a segment may be used as at least part of the descriptor of the segment. In another example, some of the artificial neurons of the segment may be selected, for example based on the values associated with the artificial neurons (for example, selecting the artificial neurons associated with the highest and/or lowest values and/or median value and/or mode value), and at least part of the values associated with the selected artificial neurons may be used as at least part of the descriptor of the segment and/or in the calculation of the descriptor of the segment.

For example, at least part of the descriptors of the segments of the artificial neural network may be aggregated into a mathematical set of values, and the mathematical set may be used as at least part of the descriptor of the artificial neural network. In another example, an average or a weighted average of at least part of the descriptors of the segments of the artificial neural network may be calculated, optionally according to weights assigned to the segments (for example according to a function of the number of artificial neurons in each segment, where examples of the function may include a polynomial function, a log function, an exponential function, and so forth), and the calculated average and/or weighted average may be used as at least part of the descriptor of the artificial neural network. In another example, the distribution of at least part of the descriptors of the segments of the artificial neural network and/or the properties of said distribution may be used as at least part of the descriptor of the artificial neural network. In yet another example, a histogram of at least part of the descriptors of the segments of the artificial neural network may be used as at least part of the descriptor of the artificial neural network. In another example, some of the segments of the artificial neural network may be selected, for example based on their descriptors, and at least part of the descriptors of the selected segments may be used as at least part of the descriptor of the artificial neural network and/or in the calculation of the descriptor of the artificial neural network. In yet another example, a hash value produced by a hash function of at least part of the descriptors of the segments of the artificial neural network may be used as at least part of the descriptor of the artificial neural network. Some examples of such properties may include mean, mode, median, standard deviation, variance, and so forth.
In some examples, a graph and/or a hypergraph of the segments of the artificial neural network may be constructed, for example where the nodes correspond to the segments, and where the edges and/or hyperedges are constructed according to the structure of the artificial neural network and the connections among the segments in the artificial neural network. For example, segments with common artificial neurons may be connected by an edge and/or a hyperedge. In another example, two segments may be connected with a directed edge if one of the two segments feeds input to the other segment. In some examples, nodes of the graph and/or hypergraph may be labeled with the descriptors of the corresponding segments. In some examples, edges and/or hyperedges of the graph and/or hypergraph may be labeled with the descriptors of the segments corresponding to the nodes connected by the edges and/or hyperedges. The graph and/or hypergraph, with or without labels associated with the nodes and/or edges and/or hyperedges, may be used as at least part of a descriptor of the artificial neural network.
In some embodiments, the descriptors of the segments of the artificial neural network may be constructed recursively. For example, denote a segment as a sub-segment of another segment if all the artificial neurons of the sub-segment are also in the other segment. In some examples, a single artificial neuron may be considered a segment, and the descriptor of a segment comprising a single artificial neuron may be calculated as described above in Step 1130. Further, some segments may include sub-segments, in the recursive step these segments may be treated as a complete artificial neural network, and the descriptors of these segments may be constructed as described above in Step 1140.
In some embodiments, calculating a match score for a pair of artificial neural networks (Step 1150) may comprise comparing the descriptor of a first artificial neural network with a descriptor of a second artificial neural network to obtain a matching score. For example, the descriptors of the first artificial neural network and/or the second artificial neural network may be constructed by Step 1140 as described above. In another example, at least part of the descriptors of the first artificial neural network and/or the second artificial neural network may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In yet another example, at least part of the descriptors of the first artificial neural network and/or the second artificial neural network may be received from external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In some examples, the second artificial neural network may comprise a result of using a machine learning algorithm to update the first artificial neural network using a plurality of training examples. In another example, the two artificial neural networks may be two different results of using machine learning algorithms to train identical or similar artificial neural networks (for example using the same deep learning algorithm and/or using different deep learning algorithms, using the same plurality of training examples and/or using different pluralities of training examples, using the same hyper-parameters and/or using different hyper-parameters, and so forth).
In some examples, a descriptor of an artificial neural network may comprise a mathematical set, and comparing the descriptors may comprise comparing the mathematical sets, for example by counting the number of common elements in the two sets and dividing that with the average number of elements in a set, by measuring the average (over all elements of the first set) of the maximal similarity between an element of the first set and any element in the second set, and so forth. In some examples, a descriptor of an artificial neural network may comprise an n-tuple of values (for example, a single value, a hash value, a list of histogram values, a list of selected values, a list of properties of a distribution, and so forth), and comparing the descriptors may comprise comparing the n-tuples, for example by calculating a distance and/or a divergence between the two n-tuples. Some examples of such distances and/or divergences may include mean absolute differences, mean squared differences, root mean squared differences, Kullback-Leibler divergence, Jensen-Tsallis divergence, and so forth. In some examples, a descriptor of an artificial neural network may comprise a distribution (for example, as described above), and comparing the descriptors may comprise calculating a statistical distance (such as f-divergence, Kullback-Leibler divergence, Hellinger distance, Total variation distance, Rényi's divergence, Jensen-Shannon divergence, Lévy-Prokhorov metric, Bhattacharyya distance, Kantorovich metric, Tsallis divergence, etc.) between the distributions.
In some examples, a descriptor of an artificial neural network may comprise a graph and/or a hypergraph, and comparing the descriptors may comprise using an inexact graph matching and/or an inexact hypergraph matching algorithms to obtain a matching score for the two artificial neural networks. In some examples, a descriptor of an artificial neural network may have a recursive structure, and comparing the descriptors may comprise a recursive comparison function that combines the results of the comparison of the immediate sub-descriptors of the two descriptors into a comparison of the two descriptors.
In some embodiments, selecting an action based on the matching score (Step 1160) may comprise selecting and/or performing one or more actions based on the matching score and/or comparison result of Step 1150. For example, the matching score and/or comparison result of Step 1150 may be compared with a selected threshold to determine whether the two artificial neural networks are similar or not. Further, some actions may be performed in response to the determination that the two artificial neural networks are similar, while some other actions may be performed in response to the determination that the two artificial neural networks are dissimilar. In another example, a rule (such as a lookup-table and/or a switch expression) that selects actions according to ranges of matching score values may be used to select actions according to the matching score and/or comparison result of Step 1150.
In some examples, one action that may be selected and/or performed by Step 1160 may comprise utilizing one of the artificial neural networks compared by Step 1150, for example as described in Step 1050. For example, Step 1160 may utilize the second artificial neural network of the comparison of Step 1150 when the two artificial neural networks are found to be similar, when the two artificial neural networks are found to be dissimilar, when the matching score of the two artificial neural networks is in a selected range of values, and so forth.
In some examples, one action that may be selected and/or performed by Step 1160 may comprise forgoing the usage of one of the artificial neural networks compared by Step 1150 in one or more tasks, for example as described in Step 1060. For example, Step 1160 may forgo the usage of the second artificial neural network of the comparison of Step 1150 in one or more tasks when the two artificial neural networks are found to be similar, when the two artificial neural networks are found to be dissimilar, when the matching score of the two artificial neural networks is in a selected range of values, and so forth.
In some examples, one action that may be selected and/or performed by Step 1160 may comprise informing a user, for example about the comparison result, about the matching score, and so forth. For example, Step 1160 may inform the user when the two artificial neural networks are found to be similar, when the two artificial neural networks are found to be dissimilar, when the matching score of the two artificial neural networks is in a selected range of values, and so forth. In some examples, the process may inform the user about the comparison result regardless of the matching score.

In some examples, at least part of the properties of a machine learning training task may be received from another process. In some examples, at least part of the properties of a machine learning training task may be obtained from datasets 610 and/or annotations 620 and/or views 630 and/or algorithms 640 and/or tasks 650. For example, the properties of a machine learning training task may include identifiers of a machine learning algorithm of algorithms 640 and/or an identifier of a machine learning training task of tasks 650, and in some cases additional properties of the machine learning training task may be obtained from the identified algorithm and/or task. In another example, the properties of a machine learning training task may include identifiers of a dataset of datasets 610 and/or an annotation of annotations 620 and/or a view of views 630. In some examples, the identified dataset and/or annotation and/or view may serve as at least part of the a training set and/or a validation set and/or a test set, and in some cases additional properties of the a training set and/or a validation set and/or a test set may be obtained from datasets 610 and/or annotations 620 and/or views 630. In some examples, the identified dataset and/or annotation and/or view may be split into a training set and/or a validation set and/or a test set according to a rule (which may also be specified in the properties of the machine learning training task). For example, such rule may specify the amount of examples in each set.
Some examples of properties of a machine learning training task may include a type of a machine learning algorithm, hyper-parameters of the machine learning algorithm, properties of the training set, properties of the validation set, properties of the test set, and so forth. The hyper-parameters of the machine learning algorithm may differ from one machine learning algorithm to another. For example, some examples of hyper-parameters of an artificial neural network may include the structure of the artificial neural network (such as the number of layers, the size of each layer, a graph defining the structure of the network, and so forth), optimizer, loss function, weight decay function, the types of the network's artificial neurons, hyper-parameters of the network's artificial neurons, initialization data, learning rate, dropout, stopping condition, number of epochs, batch size, momentum, random seed, and so forth. In another example, some examples of hyper-parameters of a support vector machine model may include kernel function, optimizer, penalty function, penalty weight, stopping condition, and so forth. In yet another example, some examples of hyper-parameters of an AdaBoost algorithm may include base classifier, maximum number of base classifiers in the model, learning rate, optimization algorithm, random seed, and so forth. In another example, some examples of hyper-parameters of a k-means model may include number of clusters, initial guess, and so forth.

In some embodiments, obtaining properties of external devices (Step 1220) may comprise obtaining at least one property of one or more external devices. For example, Step 710 may be used to obtain information associated with the external devices, as described above. In another example, Step 910 may be used to obtain available processing resources information of the external devices, as described above.
In some embodiments, estimating processing resources requirements (Step 1230) may comprise estimating at least one processing resources requirement associated with a machine learning training task based on the at least one property of the machine learning training task obtained by Step 1210 and/or the at least one property of one or more external devices obtained by Step 1220. For example, the processing time and/or memory size and/or communication bandwidth and/or communication throughput required for performing a machine learning training task may be estimated. In some examples, Step 1230 may use a function that takes as input at least part of the properties of the machine learning training task and/or at least part of the properties of the external devices, and outputs estimated processing resources requirements in response. For example, the function may be defined and/or programmed manually. In another example, the function may use k-nearest neighbors approach, searching for the k most similar samples in a database that stores examples of processing resources requirements for different properties of the machine learning training tasks and/or different properties of devices (for example according to past experience), and combining the processing resources requirements of the k selected samples to obtain the estimated processing resources requirements. In yet another example, to obtain the function, a machine learning algorithm may be trained using a dataset of training example, each training example may comprise properties of the machine learning training tasks and/or properties of the devices (for example according to past experience), together with the corresponding processing resources requirements. In another example, the function may comprise an artificial neural network configured to predict the processing resources requirements from the properties of the machine learning training tasks and/or the properties of the devices. In some examples, the function may estimate the processing resources requirements based on properties of the machine learning training tasks for a baseline device, and may adjust the estimated processing resources requirements to a different device according to a correction function. The correction function may be configured to adjust the required processing resources of the baseline device to the required processing resources of a different device, for example according to past experience. For example, the correction function may multiply the processing time by a factor, where the factor is selected based on the number of instructions per a time unit that the baseline device can perform and that the different device can perform according to some benchmark. In some examples, the correction function may multiply the processing time by a factor, where the factor is selected based on the number of processing cores in the baseline device and the number of processing cores in the other device. For example, assuming that the baseline device has m processing cores, and that the other device has n processing cores, the correction factor may be selected to be (m/n) to the power of c, where c is a number between zero and one expressing the inefficiency of distributed processing, which may depend on the properties of the machine learning training tasks. In some examples, the estimated processing resources requirements may comprise a range of estimated processing resources requirements together with a distribution that assigns probabilities to the estimations. For example, the properties of the devices may comprise a distribution of properties, and a function of the distribution of properties may produce a distribution of estimated processing resources requirements. In another example, the machine learning training task may comprise a probabilistic component dictating the processing resources requirements, and the distribution of the probabilistic component may translate into a distribution of estimated processing resources requirements.
In some embodiments, providing the estimation (Step 1240) may comprise providing the estimated processing resources requirements of Step 1230 and/or information based on the estimated processing resources requirements to a user, to another process, to an external device, and so forth. In some examples, the information may be provided to a user visually, for example using a graphical user interface, using a web site, using a display system, using an augmented reality system, using a virtual reality system, in a printed form, and so forth. In some examples, the information may be provided audibly, for example through audio speakers, using headset, and so forth. In some examples, the information may be transmitted to an external device, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In some examples, the information may be provided to another process (for example through a memory module, such as memory units 210, shared memory modules 410, and so forth). In some examples, the information may be provided selectively, for example providing the information when the estimated processing resources requirements are in a selected range, and forgoing providing the information otherwise.
In some embodiments, selecting a device (Step 1250) may comprise selecting at least one device, for example based on the estimated processing resources requirements of Step 1230. In some examples, Step 1230 may be repeated to obtain a plurality of estimated processing resources requirements for a plurality of devices, and at least one device of the plurality of devices may be selected according to their corresponding estimated processing resources requirements. For example, some constraints on the estimated processing resources requirements may be obtained (for example from tasks 650, from a user, from an external device, from another process, from a memory unit, and so forth), and the selected at least one device may include devices that satisfy the constraints. Some examples of such constraints may include maximal processing time, maximal memory size, and so forth. In another example, using process 1600 it may be determined that process 1200 has no permission to use some devices, and as a result different devices may be selected. In yet another example, using process 1700 it may be determined that process 1200 has insufficient quota to use some devices, and as a result different devices may be selected. In another example, a cost function may be used to assign cost for each one of the plurality of devices according to their corresponding estimated processing resources requirements, and the device corresponding to the lowest cost (possibly out of the devices that satisfy the constraints as described above) may be selected. An example of such a cost function may include c1*t+c2*s, where c1 and c2 are positive constants which may represent cost per processing time and cost per memory size respectively, t may represent the estimated processing time, and s may represent the estimated memory size. In some examples, the estimated processing resources requirements may comprise an estimated range of processing resources requirements together with a distribution that assigns probabilities to the estimations. In such cases, the constraints may specify a required certainty that some other conditions hold. Further, the cost function may comprise a function that sums values over the different estimations according to the probabilities. In some examples, Step 1250 may determine that there is no available device that satisfies the constraints. In response to such determination, Step 1250 may forgo Step 1260, may provide a failure indication (for example, to a user, to process 1800, etc.), and so forth.
In some embodiments, causing the selected device to perform the training task (Step 1260) may comprise causing the devices selected by Step 1250 to perform the machine learning training task of Step 1210. In some examples, a message may be transmitted to the selected devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, etc.), and the message may be configured to cause the selected devices to perform the machine learning training task. For example, the message may comprise at least part of the machine learning training task information, an indication of the machine learning training task, and so forth. For example, the machine learning training task may comprise generating and/or updating an inference model by training a machine learning algorithm using training examples. In some examples, Step 1260 may provide a progress update to process 1800, comprising details of the dispatched training task.
In some embodiments, a decision whether or not to perform the machine learning training task may be made. For example, Step 1250 may find no device that satisfies the constraints, and as a result it may decide not to perform the machine learning training task. In another example, Step 1250 may find that the value of a cost function for all the devices is above some selected threshold, and as a result it may decide not to perform the machine learning training task. In yet another example, the estimated processing resources requirements for the machine learning training task calculated by Step 1230 may be compared to some estimated processing resources requirements of some alternative machine learning training tasks, and as a result it may be decided (for example, according to some rules) to perform one of the alternative machine learning training tasks instead of the machine learning training task of Step 1210. In another example, the estimated processing resources requirement of Step 1230 may comprise a distribution of estimated processing resources requirements, and the decision to perform the machine learning training task may be based on a probability that an estimated processing resources requirement is below a selected threshold according to the distribution. In some examples, it may be decided to perform the machine learning training task when the value of a cost function calculated by Step 1250 for at least one device is below the selected threshold. In some examples, in response to a decision to perform the machine learning training task, Step 1260 may be performed. In some examples, in response to a decision not to perform the machine learning training task, the system may forgo Step 1260.
In some embodiments, obtaining intermediate results of training machine learning algorithms (Step 1310) may comprise obtaining intermediate results of training at least one machine learning algorithm using a plurality of training examples. In some examples, at least part of the intermediate results may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the intermediate results may be obtained from logs 660. In yet another example, at least part of the intermediate results may be received from external devices (for example from devices that trained the machine learning algorithms using the plurality of training examples), for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In another example, at least part of the intermediate results may be obtained by training the machine learning algorithms using the plurality of training examples. For example, the machine learning algorithms may be read from memory (such as memory units 210, shared memory modules 410, and so forth), received from external devices (for example using communication devices, such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth), obtained from algorithms 640, and so forth. Further, the plurality of training examples may be read from memory (such as memory units 210, shared memory modules 410, and so forth), received from external devices (for example using communication devices, such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth), obtained from datasets 610 and/or annotations 620 and/or views 630, and so forth.
In some examples, the intermediate results may comprise values of parameters of the machine learning algorithm. In some examples, the intermediate results may comprise values measured using at least part of the training examples and/or using at least part of the validation examples and/or using at least part of the test examples, such as a value of a loss function, a value of a cost function, a value of an objective function, precision, recall, accuracy, specificity, F1 score, confusion matrices, number and/or ratio of true positives, number and/or ratio of false positives, number and/or ratio of false negative, number and/or ratio of true negatives, and so forth. For example, the machine learning algorithm may minimize an objective function and/or maximize an objective function, and the intermediate results may comprise an intermediate value of the objective function in the minimization and/or maximization process (for example using an optimization scheme, such as gradient descent, stochastic gradient descent, coordinate descent, and so forth). In some examples, the intermediate results may comprise intermediate states of the machine learning algorithms. In some examples, the intermediate results may comprise an intermediate inference model and/or information based on an intermediate inference model. For example, the machine learning algorithm may search an inference model in a mathematical space of inference model (for example using an optimization scheme, such as gradient descent, stochastic gradient descent, coordinate descent, and so forth), and an intermediate inference model may be an intermediate result of the search. In some examples, the intermediate results may comprise the results of applying data items (such as training examples, validation examples, test examples, and so forth) to the intermediate inference model.
In some embodiments, obtaining additional training examples based on intermediate results (Step 1320) may comprise obtaining at least one additional training example based on the intermediate results obtained by Step 1310. In some examples, the additional training examples may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In some examples, the intermediate results may be provided to another process, and the additional training examples may be received in response. In some examples, the additional training examples may be obtained and/or selected from datasets 610 and/or annotations 620 and/or views 630, and so forth. In some examples, the intermediate results may be transmitted to external devices, and in response the additional training examples may be received from the external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). For example, the external devices may capture additional training examples, for example according to the intermediate results using at least one sensor (such as audio sensors 250, image sensors 260, motion sensors 270, positioning sensors 275, barometers, pressure sensors, proximity sensors, electrical impedance sensors, electrical voltage sensors, electrical current sensors, and so forth). For example, the intermediate results may indicate some conditions in which an intermediate inference model is more prone to errors, and the additional training examples may be captured in the indicated conditions.
In some examples, the additional training examples may be selected of a plurality of alternative training examples based on the intermediate results obtained by Step 1310. For example, the intermediate results may comprise a confusion matrix, and an analysis of the confusion matrix may indicate that one or more classes are more prone to error. In response, additional training examples may be selected for the classes that are more prone to errors. In another example, the intermediate results may comprise an intermediate inference model, and additional training examples for which the intermediate inference model provides wrong classification and/or regression results may be selected. In yet another example, the intermediate results may comprise training examples and/or a validation examples for which an intermediate inference model provides wrong classification and/or regression results, and additional training examples that are similar (for example, under some similarity measure) to those training examples and/or a validation examples may be selected.
In some examples, a dataset and/or an annotation and/or a view may be selected from datasets 610 and/or annotations 620 and/or views 630 based on the intermediate results obtained by Step 1310. The entire set of examples in the selected dataset and/or the selected annotation and/or the selected view may be used as additional training examples, or the additional training examples may be selected of the selected dataset and/or the selected annotation and/or the selected view (for example as described above). For example, the intermediate results may comprise a confusion matrix, and an analysis of the confusion matrix may indicate that one or more classes are more prone to error. In response, a dataset and/or an annotation and/or a view associated with the classes that are more prone to error may be selected.
In some examples, the additional training examples may be generated based on the intermediate results obtained by Step 1310. For example, the intermediate results may comprise a confusion matrix, and an analysis of the confusion matrix may indicate that one or more classes are more prone to error. In response, additional training examples may be generated for the classes that are more prone to errors, for example using the Synthetic Minority Over-sampling Technique (SMOTE) algorithm, using a generative model, and so forth. In another example, the intermediate results may comprise an intermediate inference model, and synthetic additional training examples for which the intermediate inference model provides wrong classification and/or regression results may be generated (for example, by generating an excess number of synthetic examples, and selecting the ones that correspond to wrong classification and/or regression results out of the generated examples).
In some embodiments, Step 1320 may obtain additional training examples based on the intermediate results obtained by Step 1310 and quota record. For example, at least some of a plurality of alternative training examples may be associated with a quota required for using them and/or a price. Step 1320 may select the additional training examples of the plurality of alternative training examples such that the quota usage and/or cost is minimized, the quota usage and/or cost is below a selected threshold, and so forth. For example, Step 1320 may select the additional training examples by solving an optimization problem that maximizes some objective function associated with the content of the selected training examples, while minimizing and/or bounding the quota usage and/or cost.
In some embodiments, training the machine learning algorithm using the obtained additional training examples (Step 1330) may comprise training the machine learning algorithms of Step 1310 using the additional training examples obtained by Step 1320. For example, a message may be transmitted to external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, etc.), and the message may be configured to cause the external devices to train the machine learning algorithms using the additional training examples. For example, the message may comprise at least part of the machine learning algorithms information, an indication of the machine learning algorithms, an intermediate state of the machine learning algorithms (for example, as obtained by Step 1310), an intermediate inference model, at least part of the additional training examples, indication of the additional training examples, and so forth. In another example, a similar message may be provided to another process (for example through a memory module, such as memory units 210, shared memory modules 410, etc.), and may be configured to cause the other process to train the machine learning algorithms using the additional training examples.
In some examples, Step 1310 may obtain intermediate results of training the machine learning algorithms using a first group of training examples, and Step 1330 may comprise training the machine learning algorithms using the additional training examples without the first group of training examples, or training the machine learning algorithms using the additional training examples and at least part of the first group of training examples. In some examples, training the machine learning algorithms using the additional training examples may comprise updating an intermediate inference model obtained by Step 1310 using the machine learning algorithms, the additional training examples (in some cases together with at least part of the first group of training examples used to produce the intermediate inference model). In some examples, training the machine learning algorithms using the additional training examples may comprise initializing the machine learning algorithms according to an intermediate state of the machine learning algorithms obtained by Step 1310, and providing to the initialized machine learning algorithms the additional training examples (in some cases together with at least part of the first group of training examples used to produce the intermediate state) as input to be used for training.
In some embodiments, process 1300 may determine that external intervention is required. As a result, process 1300 may provide a request to provide new training examples, for example, to another process, to an external device, to a user (for example, through a user interface, through another process, through an external device, etc.), and so forth. In response, process 1300 may obtain the requested new training examples, for example from the other process, from the external device, from the user (for example, through a user interface, through another process, through an external device, etc.), and so forth. Further, process 1300 may train a machine learning algorithm using the new training examples, for example using Step 1330. In some examples, process 1300 may determine that external intervention is required based on a determination that the quality of the additional training examples obtained by Step 1320 is below a selected threshold. For example, Step 1320 may further obtain confidence levels corresponding to the additional training examples (to be used as a quality measure), for example from a process used to generate the additional training examples, from a process used to select the additional training examples, from an inference model trained to assign confidence levels to additional training examples, and so forth. In another example, the similarity of the additional training examples to a plurality of training examples used to produce the intermediate results of Step 1310 may be calculated, and the quality of the additional training examples may be based on the calculated similarity (for example, the quality may be a monotonically decreasing function of the calculated similarity, denoted s, such as −s, −s*s*s, exp(−s/c) for some constant c, and so forth). In some examples, process 1300 may determine that external intervention is required based on the intermediate results obtained by Step 1310. For example, the intermediate results may be compared with previous intermediate results, and when there are too similar according to some selected threshold process 1300 may determine that the external intervention is required. In another example, the intermediate results may comprise an intermediate inference model, and a measurement of the quality of the intermediate inference model (such as precision, recall, accuracy, specificity, F1 score, confusion matrix, number and/or ratio of true positives, number and/or ratio of false positives, number and/or ratio of false negative, number and/or ratio of true negatives, and so forth) may be obtained (for example, calculated, obtained from the intermediate results, obtained using process 1000, and so forth), and the process may determine that external intervention is required when the quality of the intermediate inference model is below a selected threshold. In some examples, process 1300 may select a user of a plurality of alternative users, for example based on the intermediate results, and provide the request for new training examples to the selected user. For example, the intermediate results may comprise an intermediate inference model, a measurement of the quality of the intermediate inference model may be obtained as described above, and a user may be selected based on the range of values that the measurement of the quality is in.
In some embodiments, obtaining a group of labeled examples and a group of unlabeled examples (Step 1410) may comprise obtaining a group of a plurality of labeled examples and a group of a plurality of unlabeled examples. For example, at least part of the labeled examples and/or at least part of the unlabeled examples may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the labeled examples and/or at least part of the unlabeled examples may be obtained from datasets 610 and/or annotations 620 and/or views 630. In yet another example, at least part of the labeled examples and/or at least part of the unlabeled examples may be received from external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). For example, at least part of the labeled examples and/or at least part of the unlabeled examples received from the external devices may be based on and/or comprised of information captured by the external devices (for example using at least one sensor, such as audio sensors 250, image sensors 260, motion sensors 270, positioning sensors 275, barometers, pressure sensors, proximity sensors, electrical impedance sensors, electrical voltage sensors, electrical current sensors, and so forth). In some examples, at least part of the labeled examples and/or at least part of the unlabeled examples may be generated, for example using a generative model. In some examples, at least part of the group of labeled examples may be obtained using process 1500 and/or Step 1510.
In some embodiments, generating an inference model using the group of labeled examples (Step 1420) may comprise generating the inference model using at least part of the group of labeled examples obtained by Step 1410. In some examples, the inference model may comprise a classification model and/or a regression model. In some examples, a machine learning algorithm (such as a classification machine learning algorithm, a regression machine learning algorithm) may be trained using at least part of the group of labeled examples to produce the inference model. For example, at least part of the group of labeled examples may be used as a training set and/or a validation set and/or a test set. In another example, at least part of the group of labeled examples may be split into at least two of the following sets: training set, validation set, and test set. In some examples, a message may be transmitted to external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, etc.), the message may be configured to cause the external devices to train the machine learning algorithm using at least part of the group of labeled examples, and in response the inference model may be received from the external devices. For example, the message may comprise at least part of the machine learning algorithm information, an indication of the machine learning algorithm, at least part of the group of labeled examples, indication of the labeled examples, indication of the group of labeled examples, and so forth. In another example, such message may be provided to another process (for example through a memory module, such as memory units 210, shared memory modules 410, etc.), the message may be configured to cause the other process to train the machine learning algorithm using at least part of the group of labeled examples, and in response the inference model may be received from the other process.
In some embodiments, assigning labels to at least part of the group of unlabeled examples (Step 1430) may comprise using the inference model generated by Step 1420 to assign labels to at least part of the unlabeled examples of the group of unlabeled examples obtained by Step 1410. For example, the unlabeled examples may be applied to the inference model, and the output of the inference model for the unlabeled examples may be used as labels of the unlabeled examples. In some examples, the unlabeled examples may be applied to a plurality of inference models, and the labels for the unlabeled examples may be selected through a voting process using the results obtained from the plurality of inference models. In some examples, a message may be transmitted to external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, etc.), the message may be configured to cause the external devices to assign labels to at least part of the unlabeled examples of the group of unlabeled examples obtained by Step 1410 (for example using the inference model generated by Step 1420), and in response labels for the unlabeled examples may be received from the external devices. For example, the message may comprise at least part of the inference model information, an indication of the inference model, at least part of the group of unlabeled examples, an indication of the unlabeled examples, an indication of the group of unlabeled examples, and so forth. In another example, such message may be provided to another process (for example through a memory module, such as memory units 210, shared memory modules 410, etc.), the message may be configured to cause the other process to assign labels to at least part of the unlabeled examples of the group of unlabeled examples obtained by Step 1410 (for example using the inference model generated by Step 1420), and in response labels for the unlabeled examples may be received from the other process.
In some examples, at least some of the labeled examples of the group of labeled examples and/or at least some of the unlabeled examples of the group of unlabeled examples may comprise image data (for example, images captured using image sensors 260). In some cases, the inference model generated by Step 1420 may comprise a detector configured to detect items in images (such as faces, people, objects, text, and so forth), and the labels assigned to the image by Step 1430 may comprise an indicator whether an item was detected in the image, a list of items detected in the image, locations of the items detected in the image, and so forth. In some cases, the inference model generated by Step 1420 may comprise a recognition model, and the labels assigned to the image by Step 1430 may comprise identifying information of people depicted in the image. In some cases, the inference model generated by Step 1420 may comprise a segmentation model, and the labels assigned to the image may comprise a segmentation of the image. In some cases, the inference model generated by Step 1420 may comprise an image regression model, and the labels assigned to the image may comprise another image (for example, a transformed version of the image obtained by applying the original image to the image regression model). For example, the image regression model may comprise a super resolution model, and the label may comprise an enlarged version of the original image. In another example, the image regression model may comprise an image enhancement model, and the label may comprise an enhanced version of the original image. In yet another example, the image regression model may comprise an image filter, and the label may comprise a filtered version of the original image.
In some embodiments, assigning confidence levels to the assigned labels (Step 1440) may comprise calculating confidence levels corresponding to the labels assigned by Step 1430 to at least part of the unlabeled examples of the group of unlabeled examples obtained by Step 1410. For example, Step 1430 may assign labels by applying the unlabeled examples to an inference model, and the inference model may be configured to output labels together with confidence levels. In another example, Step 1430 may assign labels by applying the unlabeled examples to a plurality of inference models, selecting the labels to be assigned to the unlabeled examples through voting, and calculating the confidence level according to the distribution of the results obtained from the plurality of inference models, for example by taking the ratio of the selected label out of the total number of results as the confidence level, by taking a function of the number of repetitions of the selected label and the total number of results as the confidence level, and so forth. In some examples, Step 1430 may obtain the labels for the unlabeled examples from external devices and/or from another process, and the confidence levels may also be obtained from the external devices and/or from the other process. In some examples, at least part of the confidence levels may be obtained using Step 1520.
In some embodiments, selecting a subset of the group of unlabeled examples using the confidence levels (Step 1450) may comprise selecting a subset of the group of unlabeled examples obtained by Step 1410 and/or that were assigned with labels by Step 1430 based on the confidence levels assigned by Step 1440 and/or the labels assigned by Step 1430 and/or the content of the unlabeled examples. For example, a single example, two examples, three examples, four examples, or more than four examples, may be selected. In some examples, the number of selected examples may be calculated according to the number of labeled examples (for example, in the group of labeled examples of Step 1410, that were used by step 1420, and so forth) and/or the number of unlabeled examples (for example, in the group of unlabeled examples of Step 1410, that were assigned with a label by Step 1430, and so forth). For example, the number of selected examples may be a function of the number of labeled examples, denoted n1, and the number of unlabeled examples, denoted n2. For a positive constant c (such as 1.4, 2, 4, 10, 20, 100, and so forth), some examples of such function may include, round(n1/c), round(n2/c), round(min(n1,n2)/c), and so forth.
In some examples, the unlabeled examples corresponding to the highest confidence levels may be selected. In some examples, the labels may include assignment of examples to a finite number of classes. For each class, a desired number of examples for a class may be determined (which may also be zero), and the desired number of examples that correspond to the highest confidence levels of the examples that were assigned to that class by Step 1430 may be selected. For example, the desired number of examples for a class may be calculated as a function of the number of examples that were assigned to the class by Step 1430, the number of examples assigned to the class in the group of labeled examples, the total number of examples that were assigned with any label by Step 1430, the total number of examples in the group of labeled examples of Step 1410, the total number of examples in the group of unlabeled examples of Step 1410, and so forth.
In some examples, the labels may include assignment of numbers from a range of possible values (for example by a regression model) to examples. Some sub-ranges of values may be selected, for each sub-range a desired number of examples may be determined (which may also be zero), and the desired number of examples that correspond to the highest confidence levels of the examples that were assigned with values in that sub-range by Step 1430 may be selected. For example, the desired number of examples for a sub-range may be calculated as a function of the number of examples that were assigned to values in that sub-range by Step 1430, the number of examples assigned to values in that sub-range in the group of labeled examples, the total number of examples that were assigned with any value by Step 1430, the total number of examples in the group of labeled examples of Step 1410, the total number of examples in the group of unlabeled examples of Step 1410, and so forth.
In some examples, the unlabeled examples may be assigned to clusters (for example according to the content of the unlabeled examples, as determined by a clustering algorithm applied to the unlabeled examples), for each cluster, a desired number of examples per cluster may be determined (which may also be zero), and the desired number of examples that correspond to the highest confidence levels of the examples that were assigned to that cluster may be selected. For example, the desired number of examples per cluster may be calculated as a function of the number of examples that were assigned to the cluster, the number of examples assigned to the cluster in the group of labeled examples, the total number of examples that were assigned with any value by Step 1430, the total number of examples in the group of labeled examples of Step 1410, the total number of examples in the group of unlabeled examples of Step 1410, and so forth.
In some examples, some examples of the group of labeled examples of Step 1410 that are wrongly treated by the inference model generated by Step 1420 (for example, assigned with the wrong class by a classification model, assigned with a value that is beyond a selected threshold of difference from a ground truth value by a regression model, and so forth) may be selected. Further, for each selected wrongly treated example, unlabeled examples that correspond to the highest confidence levels may be selected of a group of unlabeled examples that are the most similar (under some similarity measure) to the wrongly treated example (for example, of the unlabeled examples that were assigned with values by Step 1430, of the group of unlabeled examples of Step 1410, and so forth).
In some embodiments, generating a second inference model (Step 1460) may comprise generating a second inference model using at least part of the group of labeled examples obtained by Step 1410 and/or the subset of the group of unlabeled examples selected by Step 1450 and/or the labels assigned by Step 1430 to the examples in the selected subset of the group of unlabeled examples. In some examples, the second inference model may comprise a classification model and/or a regression model. In some examples, a machine learning algorithm (such as a classification machine learning algorithm, a regression machine learning algorithm, and so forth) may be trained and produce the second inference model using at least part of the group of labeled examples obtained by Step 1410 and/or the subset of the group of unlabeled examples selected by Step 1450 and/or the labels assigned by Step 1430 to the examples in the selected subset of the group of unlabeled examples. For example, at least part of the examples (and possibly the corresponding labels) may be used as a training set and/or a validation set and/or a test set. In another example, at least part of the examples (and possibly the corresponding labels) may be split into at least two of the following sets: training set, validation set, and test set. In some examples, the inference model generated by Step 1420 may be updated according to the subset of the group of unlabeled examples selected by Step 1450 (and possibly the labels assigned by Step 1430 to the examples in the selected subset), for example using an online and/or incremental machine learning algorithm, by changing the lost function of the machine learning algorithm according to the new training examples and using the inference model and/or an intermediate state from Step 1420 in the initialization of the machine learning algorithm, by changing the batches of examples to include the new examples in a batch based machine learning algorithm, and so forth. In some examples, a message may be transmitted to external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, etc.), the message may be configured to cause the external devices to train the machine learning algorithm using at least part of the examples (and possibly the corresponding labels), and in response the second inference model may be received from the external devices. For example, the message may comprise at least part of the machine learning algorithm information, an indication of the machine learning algorithm, at least part of the examples (and possibly the corresponding labels), indication of the examples (and possibly of the corresponding labels), and so forth. In another example, such message may be provided to another process (for example through a memory module, such as memory units 210, shared memory modules 410, etc.), the message may be configured to cause the other process to train the machine learning algorithm using at least part of the examples (and possibly the corresponding labels), and in response the second inference model may be received from the other process. In some examples, the inference model generated by Step 1420 and the second inference model generated by Step 1460 may be compared, for example using Process 1000, and in some cases the second inference model may be utilized according to the result of the comparison, for example using Step 1050 and/or Step 1060.
In some embodiments, the group of labeled examples and/or the group of unlabeled examples obtained by Step 1410 (and possibly updated along the process) may be updated according to the subset of the group of unlabeled examples selected by Step 1450, and process 1400 may repeat with the updated groups (for example, from Step 1410 or from Step 1420, possibly without the optional Step 1460). In some examples, this process may be performed once, twice, repeated until some stopping condition is met, and so forth. For example, the process may be repeated until at least a selected number of examples of the original group of unlabeled examples of Step 1410 are selected by some repetition of Step 1450. Some examples of such selected number may include a function of the original number of examples in the original group of unlabeled examples (denoted o1) and/or the original number of examples in the original group of labeled examples (denoted o2), such as o1, o1−c1, o1/c1, log(o1), min(o1, o2/c2), min(o1, o2−c2), min(o1−c1, o2−c2), min(o1/c1, o2/c2), min(o1−c1, o2/c2), min(o1/c1, o2−c2), and so forth (for some positive constants c1 and c2). Some other examples of such selected number may include a constant number (such as a number below one hundred, one hundred, a number between one hundred and one thousand, one thousand, a number between one thousand and one million, one million, a number greater than one million, and so forth). In some examples, updating the group of labeled examples and/or the group of unlabeled examples may comprise removing at least part of the examples of the selected subset from the group of unlabeled examples, adding at least part of the examples of the selected subset to the group of labeled examples, and so forth.
In some embodiments, process 1400 may determine that external intervention is required. As a result, process 1400 may provide a request to assign labels (for example, to at least part of the group of unlabeled examples of Step 1410), to another process, to an external device, to a user (for example, through a user interface, through another process, through an external device, etc.), and so forth. In response, process 1400 may obtain the requested assignment of labels, for example from the other process, from the external device, from the user (for example, through a user interface, through another process, through an external device, etc.), and so forth. Further, process 1400 may generate an inference model using the obtained assignment of labels (possibly together with additional information, such as the group of labeled examples of Step 1410), for example using Step 1460. In some examples, process 1400 may determine that external intervention is required based on a determination that the quality of the labels assigned by Step 1430 is below a selected threshold. For example, confidence levels assigned by Step 1440 may be compared with a first selected threshold, and when at least a selected number of the confidence levels are below the first selected threshold process 1400 may determine that the quality of the labels assigned by Step 1430 is below a selected threshold. In some examples, process 1400 may select a user of a plurality of alternative users, for example based on the confidence levels assigned by Step 1440, and provide the request to assign labels to the selected user. For example, a statistical measure of the confidence levels (such as mean, median, mode, etc.) may be computed, and a user may be selected based on the range of values that the statistical measure is in.
In some embodiments, obtaining assignments of labels to data-points (Step 1510) may comprise obtaining an assignment of labels to a plurality of data-points, for example to data-points of datasets 610 and/or views 630. In some examples, Step 1510 may be repeated, for example obtaining a first assignment of labels to the plurality of data-points, a second assignment of labels to the plurality of data-points, a third assignment of labels to the plurality of data-points, and so forth. In some examples, at least part of the obtained assignment of labels to data-points may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the obtained assignment of labels to data-points may be obtained from annotations 620 and/or views 630. In yet another example, at least part of the obtained assignment of labels to data-points may be received from external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In another example, at least part of the obtained assignment of labels to data-points may be generated. For example, labels may be generated for data-points by an automatic label generation method, for example of algorithms 640. One example of such automatic label generation method may include process 1400. Another example of such automatic label generation method may include Step 1530 and/or other instances of process 1500. Yet another of automatic label generation method may include applying the data-points to an inference model, and using the output of the inference model for the data-points as the assigned labels. In yet another example of automatic label generation method, at least part of the obtained assignment of labels to data-points may be interpolated and/or extrapolated from labels assigned to other data-points (for example to neighboring data-points). In some examples, at least part of the obtained assignment of labels to data-points may be obtained from one or more users (such as human labelers, for example through a data annotation tool). In some examples, at least part of the obtained assignment of labels to data-points may be based, at least in part, on information captured using at least one sensor (such as audio sensors 250, image sensors 260, motion sensors 270, positioning sensors 275, barometers, pressure sensors, proximity sensors, electrical impedance sensors, electrical voltage sensors, electrical current sensors, and so forth), where in some cases the at least one sensor may be part of one or more external devices. For example, a data-point may comprise information captured using one or more sensors, and a label may comprise associated information captured using other sensors, for example from the same environment and/or at the same time.
In some examples, at least part of the obtained assignment of labels to data-points may comprise assignments of labels to data-points by a human labeler. For example, the human labeler may assign labels to data-points using a data annotation tool. In another example, the human labeler may select assignment of labels to data-points of a plurality of alternative assignments. In some examples, at least part of the obtained assignment of labels to data-points may comprise assignments of labels to data-points by an automated process, for example as described above. In some examples, at least part of the obtained assignment of labels to data-points may comprise assignment of distributions of labels to data-points. For example, a distribution of labels may comprise a plurality of labels, where each label is accompanied with the probability that this label is the label of the data-point. In some cases, the probabilities of all the labels for a data-point may sum to one, while in other cases, some scaled and/or estimated probabilities that do not sum to one may be used. For example, a plurality of labelers (which may include human labelers, automated labeling processes, and so forth) may suggest labels to a data-point, and the assigned label may comprise the distribution of the suggested labels. In some cases, a plurality of labelers (which may include human labelers, automated labeling processes, and so forth) may suggest labels to a data-point, and the assigned label may be selected through a voting mechanism.
In some examples, past performances of labelers (such as human labelers, automated labeling processes, and so forth) may be analyzed, and the above voting mechanism may give weights to labels according to the labelers past performances. For example, the analysis may determine that the past performances of a first labeler are better than the past performances of a second labeler, and therefore give higher weight to the suggested labels of the first labeler in the voting process and/or in the aggregation of the suggested labels into a distribution of labels. In another example, the analysis may determine that the past performances of a first labeler are better than the past performances of a second labeler when dealing with a first type of data-points and/or a first type of labels, but that the past performances of the second labeler are better than the past performances of the first labeler when dealing with a second type of data-points and/or a second type of labels, and therefore give higher weight to the suggested labels of the first labeler in the voting process and/or in the aggregation of the suggested labels into a distribution of labels when dealing with the first type of data-points and/or suggested labels of the first type of labels, but give higher weight to the suggested labels of the second labeler in the voting process and/or in the aggregation of the suggested labels into a distribution of labels when dealing with the second type of data-points and/or suggested labels of the second type of labels.
In some embodiments, obtaining confidence levels (Step 1520) may comprise obtaining confidence levels associated with the assignment of labels to data-points of Step 1510. In some examples, Step 1520 may be repeated, for example obtaining a first group of confidence levels associated with a first assignment of labels to data-points, obtaining a second group of confidence levels associated with a second assignment of labels to data-points, obtaining a third group of confidence levels associated with a third assignment of labels to data-points, obtaining a fourth group of confidence levels associated with the first assignment of labels to data-points, and so forth. In some examples, at least part of the confidence levels may be obtained using Step 1440. In another example, at least part of the confidence levels may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In yet another example, at least part of the confidence levels may be received from external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In another example, at least part of the confidence levels may be generated. In some examples, at least part of the confidence levels may be generated by an algorithm of algorithms 640. For example, Step 1510 may generate at least part of the labels by applying the data-points to an inference model, and using the output of the inference model for the data-points as the assigned labels, and in some cases the inference model may further output confidence levels corresponding to the labels. In another example, at least part of the confidence levels may be interpolated and/or extrapolated from confidence levels corresponding to other data-points and/or labels.
In some examples, at least part of the confidence levels associated with an assignment of labels may comprise an assignment of confidence levels to data-points, a function that maps data-points to confidence levels, and so forth. In some examples, at least part of the confidence levels may comprise information and/or be based on information obtained from one or more users. For example, human labelers may provide labels to Step 1510, and may further provide confidence levels for the labels they provide. In another example, supervisors of human labelers may assign confidence levels to the assignment of labels. In yet another example, manual quality assurance process may assign confidence levels to an assignment of labels. In some examples, at least part of the confidence levels may comprise information and/or be based on information obtained from automated processes, for example as described above. In some examples, past performances of labelers (such as human labelers, automated labeling processes, and so forth) may be analyzed, and the confidence levels may be selected based on the past performances of the labeler that produced at least part of the assignment of labels to data-points. For example, the analysis may determine that the past performances of a first labeler are better than the past performances of a second labeler, and therefore give higher confidence level to assignment of labels produced by the first labeler than to assignment of labels produced by the second labeler. In another example, the analysis may determine that the past performances of a first labeler are better than the past performances of a second labeler when dealing with a first type of data-points and/or a first type of labels, but that the past performances of the second labeler are better than the past performances of the first labeler when dealing with a second type of data-points and/or a second type of labels, and therefore give higher confidence level to assignment of labels produced by the first labeler than to assignment of labels produced by the second labeler when dealing with the first type of data-points and/or the first type of labels, but give higher confidence level to assignment of labels produced by the second labeler than to assignment of labels produced by the first labeler when dealing with the second type of data-points and/or the second type of labels. In some cases, a plurality of labelers (which may include human labelers, automated labeling processes, and so forth) may suggest labels to a data-point, the assigned label may be selected through a voting mechanism, and the confidence level may be calculated according to the distribution of the suggested labels, for example by taking the ratio of the selected label out of the total number of suggested labels as the confidence level, by taking the weighted ratio (for example, weighted according to the past performances of the labelers, as described above) of the selected label out of the total group of suggested labels as the confidence level, by taking a function of the number of repetitions of the selected label and the total number of suggested labels as the confidence level, and so forth. In some examples, the confidence levels associated with an assignment of labels may comprise a function that maps types of data-points and/or labels to confidence levels. For example, the confidence level associated with a type of data-points and/or a label may be selected based on the past performances of the labeler that created the assignment of labels when dealing with the type of data-points and/or the label.
In some embodiments, merging the assignments (Step 1530) may comprise generating a merged assignment of labels to the plurality of data-points, for example by merging two or more assignments of labels to the plurality of data-points obtained by Step 1510, for example using the confidence levels associated with the two or more assignments of labels obtained by Step 1520 and/or the content of the data-points. In some examples, each assignment of labels to the plurality of data-points may be associated with a confidence level, and the assignment of labels that corresponds to the highest confidence level may be selected. In some examples, each assignment of labels to the plurality of data-points may be associated with an assignment of confidence levels to data-points, and for each data-point the label assigned to the data-point that corresponds to the highest confidence level of the confidence levels assigned to the data-point may be selected. In some examples, the confidence levels associated with an assignment of labels may comprise a function that maps types of data-points and/or labels to confidence levels, and generating the merged assignment of labels to the plurality of data-points may be further based on an association of types with data-points and/or on the assigned labels and/or on the function, for example by assigning confidence level to each data-point using the type of the data-point and/or the assigned label and/or the function.
In some examples, the merged assignment of labels may be a result of maximizing (or minimizing) an objective function. Denote the confidence level assigned by the i-th assignment of labels to the j-th data-point, conf(i, j), and denote the content of the j-th data-point, d(j). For example, the objective function may be a function of the confidence levels and the content of the data-points, f_1(label(1), . . . , label(J), d(1), . . . , d(J), conf(1, 1), . . . , conf(I, J)), where I is the number of assignments of labels, J is the number of data-points, and label(j) is the unknown label assigned to data-point j by the merged assignment of labels. In another example, the objective function may comprise an additively separable function comprising a continuity part and a confidence part, f_2(label(1), . . . , label(J), d(1), . . . , d(J))+f_3(label(1), . . . , label(J), conf(1, 1), . . . , conf(I, J)). For example, f_2 may include a penalty for assigning different labels to nearby data-points, and f_3 may include a penalty for assigning labels corresponding to lower confidence levels to data-points. In another example, f_3 may comprise an additively separable function comprising a term for each data-point, g_i(label(i), conf(i, 1), . . . , conf(i, J)), and f_3=g_1+ . . . +g_I. For example, g_i may be equal to a function h_i(conf(i, label(i)), conf(i, 1), . . . , conf(i, J)). For example, h_i may be equal to J*conf(i, label(i))−conf(i, 1)− . . . −conf(i, J). In another example, h_i may be equal to J*z(conf(i, label(i)))−z(conf(i, 1))− . . . −z(conf(i, J)), for some monotonically increasing function z, such as z(x)=x*x*x, z(x)=sign(x)*x*x, and so forth.
In some embodiments, obtaining and/or using assignment of labels to data-points may require usage of quota. In some examples, process 1500 may obtain the confidence levels associated with an assignment of labels using Step 1520 first, select which assignments of labels to data-points to use based on the on the confidence levels and/or the content of the data-points and/or the remaining quota (for example, as described for Step 1530, using process 1700, etc.), and then use Step 1510 to obtain the assignments of labels to data-points that were selected. In some examples, process 1500 may obtain assignments of labels to data-points using Step 1510, obtain confidence levels associated with the assignment of labels using Step 1520, and select which assignments of labels to data-points to use based on the on the confidence levels and/or the content of the data-points and/or the assigned labels and/or the remaining quota (for example, as described for Step 1530, using process 1700, etc.). For example, a term may be added to an objective function (for example, to one of the objective functions described above) to minimize the usage of quota. In another example, a constraint that limits the quota used may be added to a minimization and/or maximization problems (for example, to the minimization and/or maximization problems described above).
In some examples, Step 1530 may determine that one or more of the plurality of data-points correspond to low quality merged assignment of labels. In response to said determination, process 1530 may provide a notification. For example, the notification may identify the data-points corresponding to low quality merged assignment of labels, may include a suggestion to improve at least one of the assignment of labels obtained by Step 1510 to the data-points corresponding to low quality merged assignment of labels, and so forth. For example, the notification may be provided to a user, to a system manager, to an external device, to a different process, through logs 660, and so forth. In some examples, the determination that a data-point corresponds to low quality merged assignment of labels may be based on the assignments of labels to the data-point of Step 1510 and/or to the confidence levels associated with the data-point of Step 1520. For example, a data-point may be identified as corresponding to low quality merged assignment of labels when two conflicting labels are assigned to the data-point with similarly high confidence levels, when the highest confidence level associated with the data-point is below a selected threshold, and so forth. In some examples, the determination that a data-point corresponds to low quality merged assignment of labels may be based on a value of a term in an objective function corresponding to the data-point, such as g_i and h_i described above. For example, a data-point may be identified as corresponding to low quality merged assignment of labels when the corresponding term is below a selected threshold, above a selected threshold, low in comparison to other terms of the objective function, high in comparison to other terms of the objective function, and so forth.
In some embodiments, generating inference models using the merged assignment of labels (Step 1540) may comprise applying the merged assignment of labels generated by Step 1530 to a machine learning algorithm to obtain an inference model, for example in a similar way to what described above (for example to what described above for Step 1420).
In some embodiments, obtaining an update to the assignments of labels to data-points and/or the confidence levels (Step 1550) may comprise obtaining an update to one or more assignments of labels to data-points obtained by Step 1510 and/or to one or more confidence levels associated with assignments of labels obtained by Step 1520. For example, Step 1550 may use Step 1510 to obtain one or more updated assignment of labels to data-points and/or use Step 1520 to obtain one or more updated confidence levels. In another example, modified parts of the assignments of labels and/or confidence levels may be obtained. For example, at least part of the modified parts may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the modified parts may be received from external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In some examples, at least part of the modified parts may be generated, for example in a similar way to what described above for Step 1510 and Step 1520.
In some embodiments, updating the merged assignment (Step 1560) may comprise updating the merged assignment of labels generated by Step 1530 according to the updated assignment of labels to data-points and/or updated confidence levels obtained by Step 1550. For example, Step 1530 may be used with the updated assignment of labels to data-points and/or updated confidence levels obtained by Step 1550 to generate the updated merged assignment of labels. In some examples, Step 1560 may compare the updated assignments of labels to data-points and/or updated confidence levels obtained by Step 1550 with the original assignments of labels to data-points obtained by Step 1510 and/or the original confidence levels obtained by Step 1520 to determine if the magnitude of the update is above some selected threshold. Further, in response to a magnitude of update that is above the selected threshold, Step 1560 may update the merged assignment of labels, and in response to a magnitude of update that is below the selected threshold, Step 1560 may withhold and/or forgo updating the merged assignment of labels.
In some examples, the updated merged assignment of labels generated by Step 1560 may be applied to a machine learning algorithm to obtain an updated inference model, for example by using Step 1540 with the updated merged assignment of labels. In some examples, the inference model generated by Step 1540 and/or the updated inference model generated by Step 1560 may be utilized, for example in a similar way to what described for Step 1050. In another example, the inference model and the updated inference model may be compared, for example using process 1000 and/or process 1100. In some cases, based on the result of the comparison, the updated inference model may be utilized (for example, using Step 1050), while in other cases the process may withhold and/or forgo the utilization of the updated inference model (for example, using Step 1060).
In some embodiments, Step 1610 may comprise obtaining from an entity a request to access information in a dataset management system, such as a request to access at least part of datasets 610, annotations 620, views 630, and so forth. For example, at least part of the request may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the request may be received from external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In some examples, the entity may comprise an internal entity, an external entity, a user of the dataset management system, an automated process (such as one or more of processes 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1700 and 1800), an external device, and so forth. In some examples, the request to access information may comprise a request to read the information, a request to modify the information, a request to delete the information, and so forth. In some examples, the request to access information may comprise a request to train a machine learning algorithm using the information and/or a request to access the information for training a machine learning algorithm using the information, a request to apply the information to an inference model and/or a request to access the information for the evaluation of an inference model using the information, and so forth.
In some embodiments, Step 1610 may further comprise verifying the identity of the entity. In some examples, the request may be digitally signed (for example, cryptographically) by the entity, and the digital signature of the entity may be authenticated. In some examples, the identity of the entity may be authenticated by a third party. In some examples, a secure communication line to the entity may be used, and the communication line may be verified. In some cases, when the verification of the identity of the entity fails, process 1600 may forgo the performance of one or more steps, such as Step 1620 and/or Step 1630 and/or Step 1640. In some cases, when the verification of the identity of the entity fails, process 1600 may deny the access to the information, for example using Step 1650. In some cases, when the verification of the identity of the entity fails, process 1600 may provide a notification, for example in a response to the request, to the entity, to a user, to a system manager, through logs 660, and so forth.
In some embodiments, selecting a permission record associated with the entity (Step 1620) may comprise selecting a permission record associated with the entity of Step 1610 of a plurality of permission records (such as permission records of permissions 680). For example, at least part of the plurality of permission records may be stored in memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the plurality of permission records may be maintained by an external device and accessed using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In some examples, the plurality of permission records may be associated with a plurality of entities (for example through a data structure, in a database, etc.), and the permission record associated with the entity of Step 1610 may be selected (for example by retrieving the record from the data structure, the database, etc.). For example, each permission record may be associated with a group of entities, and the permission record that corresponds to the smallest group of entities and contains the entity of Step 1610 may be selected. In some examples, a permission record associated with the entity of Step 1610 and the information of Step 1610 may be selected. For example, each permission record may be associated with an entity (as described above) and/or a record of the dataset management system, and a permission record associated with the entity and the record of the dataset management system containing the information may be selected. In another example, each permission record may be associated with a group of entities (as described above) and/or a group of records of the dataset management system, and a the permission record that corresponds to a group of entities that contains the entity of Step 1610 and/or a group of records that contains the information may be selected. In some examples, the request to access information of Step 1610 may be associated with a machine learning algorithm (as described above), and a permission record associated with the entity and the machine learning algorithm may be selected. For example, each permission record may be associated with an entity (as described above) and/or a machine learning algorithm, and the permission record associated with the entity of Step 1610 and/or the machine learning algorithm associated with the request may be selected. In some examples, the request to access information of Step 1610 may be associated with a second entity (such as an owner and/or a creator of the information of Step 1610), and a permission record associated with the entity of Step 1610 and the second entity may be selected.
In some embodiments, Step 1620 may further comprise verifying the selected permission record. In some examples, the selected permission record may be digitally signed (for example, cryptographically) by a permissions authenticator, and the digital signature of the permissions authenticator may be verified. In some examples, a secure communication line to a permissions authenticator may be used to inquire the permissions authenticator about the permission record, and the permissions authenticator may confirm or decline the permission record. In some cases, when the verification of the permission record fails, process 1600 may forgo the performance of one or more steps (such as Step 1630 and/or Step 1640), may deny access to the information (for example using Step 1650), may provide a notification (for example in a response to the request, to the entity, to a user, to a system manager, through logs 660, etc.), and so forth.
In some embodiments, determining if the entity has permission to access the information (Step 1630) may comprise using the permission record selected by Step 1620 to determine if the entity of Step 1610 has permission to access the information. For example, the selected permission record may be analyzed to determine if the entity has permission to access the information, has permission for the requested type of access to the information, has permission to access records of the dataset management system that contains the information, has permission to use the information with a selected machine learning algorithm, has permission to use the information with a selected inference model, has permission to use the information with a selected computer function, has permission to access information associated with a second entity, and so forth. In some examples, Step 1630 may further determine if the entity has sufficient quota to access the information, for example using process 1700, using Step 1730, and so forth.
In some examples, when Step 1630 determines that the entity has permission to access the information, the flow of process 1600 may continue to allow access to the information (Step 1640). In some examples, when Step 1630 determines that the entity has no permission to access the information, the flow of process 1600 may continue to deny access to the information (Step 1650). In some examples, when Step 1630 determines that the entity has permission to access the information and has sufficient quota to access the information, the flow of process 1600 may continue to allow access to the information (Step 1640). In some examples, when Step 1630 determines that the entity has no permission to access the information and/or has insufficient quota to access the information, the flow of process 1600 may continue to deny access to the information (Step 1650) and/or to deny the request (Step 1750).
In some examples, allowing access to the information (Step 1640) may comprise allowing access to the information of Step 1610 to the entity of Step 1610. For example, according to the access request and/or the permission, at least part of the information may be provided, for example by providing a memory address of a location in a memory unit holding the at least part of the information, by transmitting the at least part of the information to the entity (for example using communication devices, over a computer network, etc.), and so forth. In another example, according to the access request and/or the permission, at least part of the information may be modified, for example according to instructions received from the entity. In yet another example, according to the access request and/or the permission, at least part of the information may be deleted. In another example, according to the access request and/or the permission, at least part of the information may be applied to a selected machine learning algorithm, to a selected inference model, to a selected computer function, and so forth. Further, the resulting outputs may be provided to the entity, for example through a memory unit, transmitted using communication devices, transmitted over a computer network, and so forth. In yet another example, according to the access request and/or the permission, at least part of the information may be used by process 700, process 800, process 900, process 1000, process 1100, process 1200, process 1300, process 1400, process 1500, process 1700, process 1800, and so forth. In some examples, Step 1640 may logging the allowed access and/or the actual access in logs 660.
In some embodiments, denying access to the information (Step 1650) may comprise withholding and/or forgoing allowing the access to the information of Step 1610 to the entity of Step 1610. In some examples, Step 1650 may log the denied access in logs 660.

For example, the provided indication may comprise a suggestion to acquire permission to access the information, possibly together with information on how to acquire the permission, together with a tool for acquiring the permission, and so forth. In another example, the provided indication may comprise a suggestion to contact an owner of the information, possibly together with the contact information of the owner (such as name, email, phone number, address, etc.), together with a tool for contacting the owner, and so forth.
In some examples, the information of Step 1610 may comprise a dataset, and the indication provided by Step 1650 may comprise a suggestion of at least one substitute dataset (for example, one substitute dataset may be suggested, a plurality of possible substitute datasets may be suggested, and so forth). In some examples, the at least one substitute dataset may be selected of a plurality of alternative datasets (for example, from datasets 610), for example based on similarity between the dataset of the information of Step 1610 and the alternative datasets. For example, a selected number of the most similar datasets of the plurality of alternative datasets may be selected as the at least one substitute dataset. In another example, all datasets with a similarity score higher than a selected threshold may be selected as the at least one substitute dataset. For example, the similarity between the dataset and an alternative dataset may be based on a statistical distance (such as f-divergence, Kullback-Leibler divergence, Hellinger distance, Total variation distance, Rényi's divergence, Jensen-Shannon divergence, Lévy-Prokhorov metric, Bhattacharyya distance, Kantorovich metric, Tsallis divergence, etc.) between the distribution of elements in the dataset and the distribution of elements in the alternative dataset.

For example, a selected number of the most similar records of annotations of the plurality of alternative records of annotations may be selected as the at least one substitute record of annotations. In another example, all records of annotations with a similarity score higher than a selected threshold may be selected as the at least one substitute record of annotations. In another example, the similarity between the record of annotations and an alternative record of annotations may be based on a statistical distance (such as f-divergence, Kullback-Leibler divergence, Hellinger distance, Total variation distance, Rényi's divergence, Jensen-Shannon divergence, Lévy-Prokhorov metric, Bhattacharyya distance, Kantorovich metric, Tsallis divergence, etc.) between the distribution of labels in the record of annotations and the distribution of labels in the alternative record of annotations. In another example, records of annotations with similar and/or identical label names and/or tag names to the label names and/or tag names of the requested record of annotations may be selected as the at least one substitute record of annotations.
In some embodiments, Step 1710 may comprise obtaining from an entity a request to perform an action in a dataset management system, such as a request to perform an action using information from the dataset management system (for example, using at least part of datasets 610, annotations 620, views 630, and so forth). For example, at least part of the request may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the request may be received from external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In some examples, the entity may comprise an internal entity, an external entity, a user of the dataset management system, an automated process (such as one or more of processes 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600 and 1800), an external device, and so forth.

In some examples, the identity of the entity may be authenticated by a third party. In some examples, a secure communication line to the entity may be used, and the communication line may be verified. In some cases, when the verification of the identity of the entity fails, process 1700 may forgo the performance of one or more steps, such as Step 1720 and/or Step 1730 and/or Step 1740. In some cases, when the verification of the identity of the entity fails, process 1700 may deny the request, for example using Step 1750. In some cases, when the verification of the identity of the entity fails, process 1700 may provide a notification, for example in a response to the request, to the entity, to a user, to a system manager, through logs 660, and so forth.

In another example, at least part of the plurality of quota records may be maintained by an external device and accessed using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In some examples, the plurality of quota records may be associated with a plurality of entities (for example through a data structure, in a database, etc.), and the quota record associated with the entity of Step 1710 may be selected (for example, by retrieving the record from the data structure, the database, etc.). In some examples, an entity may be associated with more than one quota records in the plurality of quota records, and Step 1720 may select one of the quota records associated with the entity, select the quota record with the highest quota of the quota records associated with the entity, combine the quota records associated with the entity into one quota record, and so forth. In some examples, a quota record associated with the entity of Step 1710 and the action of Step 1710 may be selected. In some examples, a quota record associated with the entity of Step 1710 and information associated with the action of Step 1710 may be selected. For example, each quota record may be associated with an entity and/or an action, and a quota record associated with the entity and the action may be selected. In another example, the requested action may comprise training a machine learning algorithm using information from the dataset management system, and the selected quota record may be associated with the entity of Step 1710 and/or the machine learning algorithm and/or the information. In yet another example, the requested action may comprise applying information from the dataset management system to an inference model, and the selected quota record may be associated with the entity of Step 1710 and/or the inference model and/or the information. In another example, the requested action may comprise calculating statistics about information from the dataset management system, and the selected quota record may be associated with the entity of Step 1710 and/or the statistical tool and/or the information.

In another example, the requested action may be associated with a second entity (such as an owner and/or a creator of information to be used, of an algorithm to be used, etc.), and the selected quota record may be associated with the entity of Step 1710 and/or the second entity.
In some embodiments, Step 1720 may further comprise verifying the selected quota record. In some examples, the selected quota record may be digitally signed (for example, cryptographically) by a quota records authenticator, and the digital signature of the quota records authenticator may be verified. In some examples, a secure communication line to a quota records authenticator may be used to inquire the quota records authenticator about the quota record, and the quota records authenticator may confirm or decline the quota record. In some cases, when the verification of the quota record fails, process 1700 may forgo the performance of one or more steps (such as Step 1730 and/or Step 1740), may deny the request (for example using Step 1750), may provide a notification (for example in a response to the request, to the entity, to a user, to a system manager, through logs 660, etc.), and so forth.
In some embodiments, determining if the entity has sufficient quota to perform the action (Step 1730) may comprise using the quota record selected by Step 1720 to determine if the entity of Step 1710 has sufficient quota to perform the requested action. In some examples, the selected quota record may be analyzed to determine if the entity has sufficient quota to perform the requested action. In some examples, a quota requirement and/or a price associated with the requested action may be obtained, and the quota requirement and/or price may be compared with the remaining quota and/or remaining budget in the quota record to determine if the entity has sufficient quota to perform the action. For example, the quota requirement and/or price associated with the requested action may be calculated according to a function that estimates quota requirements and/or prices, according to a table and/or a data structure that associate actions with quota requirements and/or prices, and so forth. In another example, the requested action may comprise performing a machine learning training task, an estimation of the processing resources requirements required for the machine learning training task may be obtained (for example, using process 1200 and/or Step 1230), and the quota requirement and/or a price associated with the requested action may be calculated using the estimated processing resources requirements. In yet another example, the requested action may comprise a usage of an inference model, quota requirement and/or a price associated with the requested action may be calculated, for example based on the identity of the inference model (for example according to a price list, through a bidding process, etc.) and/or the information required to evaluate the inference model. In another example, the requested action may comprise accessing information in the dataset management system, quota requirement and/or a price associated with the requested action may be calculated, for example based on the type of requested access (such as obtaining information, modifying information, deleting information, storing information, buying information), the type of information (data samples, annotations, datasets, etc.), the amount of information to be accessed (for example, in bytes, megabytes, gigabytes, number of examples, number of annotations, etc.), and so forth. The quota requirement and/or a price associated with the access to the information may be calculated using a price list, through a bidding process, by requesting a quote from an external entity (for example, from an entity associated with the information, such as an owner and/or creator of the information), and so forth. In some examples, the quota requirement and/or price may comprise a distribution of estimated quota requirements and/or a distribution of estimated prices, a probability that the remaining quota and/or the remaining budget in the quota record is sufficient for the action may be calculated according to the distributions, the calculated probability may be compared with a selected threshold, and Step 1730 may determine that the entity has sufficient quota to perform the action when the calculated probability is higher than the selected threshold. In some examples, Step 1730 may further determine if the entity has permission to perform the action and/or to access the information required for performing the action, for example using process 1600, using Step 1630, and so forth.
In some examples, when Step 1730 determines that the entity has sufficient quota to access the information, the flow of process 1700 may continue to allow the request (Step 1740). In some examples, when Step 1730 determines that the entity has insufficient quota to access the information, the flow of process 1700 may continue to deny the request (Step 1750). In some examples, when Step 1730 determines that the entity has sufficient quota to access the information and has permission to access the information, the flow of process 1700 may continue to allow access to the information (Step 1740). In some examples, when Step 1730 determines that the entity has insufficient quota to access the information and/or has no permission to access the information, the flow of process 1700 may continue to deny the request (Step 1750) and/or to deny access to the information (Step 1650).
In some embodiments, allowing the request (Step 1740) may comprise allowing the performance of the action of the request of Step 1710. For example, the action may be performed, for example using information from the dataset management system (such as datasets 610, annotations 620, views 630, and so forth). In another example, access to information required for the performance of the action may be provided (for example, using Step 1640). In yet another example, according to the request, information from the dataset management system (for example, from datasets 610, annotations 620, views 630, etc.) may be applied to a selected machine learning algorithm, to a selected inference model, to a selected computer function, and so forth. Further, the resulting outputs may be provided to the entity, for example through a memory unit, transmitted using communication devices, transmitted over a computer network, and so forth. In another example, according to the request, an algorithm of algorithms 640 may be used. In yet another example, according to the request, a task of tasks 650 may be performed. In another example, according to the request, a process may be executed (such as process 700, process 800, process 900, process 1000, process 1100, process 1200, process 1300, process 1400, process 1500, process 1800, and so forth). In some examples, Step 1740 may comprise logging the allowed request and/or the performance of the requested action in logs 660. In some examples, Step 1740 may update the quota record selected by Step 1720. For example, the obligated quota and/or the obligated budget of the quota record may be updated according to a quota requirement and/or a price associated with the allowed action (for example, according to the quota requirement and/or price determined by Step 1730), according to an estimated quota requirement and/or an estimated price of the allowed action (for example, as estimated by Step 1730), and so forth. In some examples, the remaining quota and/or remaining budget of the quota record may be updated according to a quota requirement and/or a price associated with the allowed action, for example after the performance of the action. For example, the actual resources used in the performance of the action may be measured, an actual quota requirement and/or an actual price may be calculated for the action according to the actual resources used, and the remaining quota and/or the remaining price may be updated according to the actual quota requirement and/or the actual price. In another example, the remaining quota and/or the remaining price may be updated according to an estimated quota requirement and/or an estimated price of the performed action (for example, as estimated by Step 1730). In some examples, once the remaining quota and/or the remaining price are updated with respect to a performed action, the obligated quota and/or the obligated budget may be updated to free the obligation associated with the performed action.
In some embodiments, denying the request (Step 1750) may comprise denying the request to perform an action of Step 1710. For example, Step 1750 may withhold and/or forgo the performance of the action. In another example, Step 1750 may withhold and/or forgo allowing access to information required for the performance of the action (for example, using Step 1650). In yet another example, Step 1750 may remove the requested action from a project schedule record, may delete a task associated with the requested action from tasks 650, and so forth. In some examples, Step 1750 may log the denied request in logs 660. In some examples, Step 1750 may provide an indication associated with the denied request, for example to the entity of Step 1710, to a user, to a system manager, and so forth. For example, the provided indication may comprise a suggestion to acquire additional quota and/or to increase the budget, possibly together with a tool for acquiring the quota and/or for increasing the budget.

In some examples, the provided indication may comprise a suggestion of at least one substitute action. In some examples, the at least one substitute action may be selected of a plurality of alternative actions (for example, from algorithm 640 and/or tasks 650), for example based on similarity between the requested action of Step 1710 and the alternative actions. For example, the most similar action of the plurality of alternative actions may be selected as the at least one substitute action.

In some examples, the action of Step 1710 may comprise access to a dataset, and the indication provided by Step 1750 may comprise a suggestion of at least one substitute dataset (for example, one substitute dataset may be suggested, a plurality of possible substitute datasets may be suggested, and so forth). In some examples, the at least one substitute dataset may be selected of a plurality of alternative datasets (for example, from datasets 610), for example based on similarity between the dataset associated with the action and the alternative datasets. For example, a selected number of the most similar datasets of the plurality of alternative datasets may be selected as the at least one substitute dataset. In another example, all datasets with a similarity score higher than a selected threshold may be selected as the at least one substitute dataset. For example, the similarity between the dataset associated with the action and an alternative dataset may be based on a statistical distance (such as f-divergence, Kullback-Leibler divergence, Hellinger distance, Total variation distance, Rényi's divergence, Jensen-Shannon divergence, Lévy-Prokhorov metric, Bhattacharyya distance, Kantorovich metric, Tsallis divergence, etc.) between the distribution of elements in the dataset associated with the action and the distribution of elements in the alternative dataset. In another example, the similarity between the dataset and an alternative dataset may be based on similarity between annotations associated with the dataset associated with the action and annotations associated with the alternative dataset.
In some examples, the action of Step 1710 may comprise access to a record of annotations, and the provided indication may comprise a suggestion of at least one substitute record of annotations (for example, one substitute record of annotations may be suggested, a plurality of possible substitute records of annotations may be suggested, and so forth). In some examples, the at least one substitute record of annotations may be selected of a plurality of alternative records of annotations (for example, from annotations 620), for example based on similarity between the record of annotations associated with the action and the alternative records of annotations. For example, a selected number of the most similar records of annotations of the plurality of alternative records of annotations may be selected as the at least one substitute record of annotations. In another example, all records of annotations with a similarity score higher than a selected threshold may be selected as the at least one substitute record of annotations. In another example, the similarity between the record of annotations associated with the action and an alternative record of annotations may be based on a statistical distance (such as f-divergence, Kullback-Leibler divergence, Hellinger distance, Total variation distance, Rényi's divergence, Jensen-Shannon divergence, Lévy-Prokhorov metric, Bhattacharyya distance, Kantorovich metric, Tsallis divergence, etc.) between the distribution of labels in the record of annotations associated with the action and the distribution of labels in the alternative record of annotations. In another example, records of annotations with similar and/or identical label names and/or tag names to the label names and/or tag names of the requested record of annotations may be selected as the at least one substitute record of annotations.
In some embodiments, obtaining a progress update (Step 1810) may comprise obtaining a progress update related to an action, for example related to an action involving data maintained by a dataset management system. For example, such action may comprise performing an algorithm of algorithms 640 and/or a task of tasks 650, for example using data from datasets 610 and/or annotations 620 and/or views 630. In some examples, at least part of the progress update may be read from memory (such as memory units 210, shared memory modules 410, and so forth). In another example, at least part of the progress update may be received from external devices (for example, from an external device performing the action and/or involved in performing the action), for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth). In yet another example, the action may comprise performing a process (such as one or more of processes 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600 and 1700), and in some cases the progress update may be obtained from the process and/or from a device performing the process.

In some examples, the progress update may be related to an action comprising usage of an inference model, for example comprising applying information to the inference model, and the progress update may comprise indications of the status of the action. For example, the information to be applied to the inference model may comprise a plurality of data-points, and the status may comprise the number and/or ratio of data-points already applied to the inference model, the number and/or ratio of data-points waiting to be applied to the inference model, the outputs (and/or statistics about the outputs) of the inference model for the data-points already applied, and so forth. In some examples, the progress update may be related to an action comprising minimizing and/or maximizing an objective function (for example, an objective function based on data from datasets 610 and/or annotations 620 and/or views 630), and the progress update may comprise indications of the status of the minimization and/or maximization. For example, the progress update may comprise intermediate results and/or intermediate status of minimization and/or maximization, such as objective value, iteration number, gradient at the intermediate result, last step size, rate of convergence, and so forth.

For example, the failure may be due to a missing and/or incompatible software (for example, missing software license, old software version, etc.), incompatible hardware (for example, insufficient memory, missing GPU, etc.), insufficient available processing resources for a machine learning training task (for example, insufficient for the estimated processing resources requirement determined by process 1230), and so forth. In another example, the failure may be due to missing and/or incompatible and/or insufficient permission and/or quota, for example as determined by process 1600 and/or process 1700. In yet another example, the failure may be due to missing and/or incompatible and/or insufficient data (for example, dataset with too few examples for a selected machine learning algorithm, dataset with no or insufficient annotations, annotations that are incompatible with a training task, and so forth). In another example, the failure may be due to a failure of a machine learning algorithm and/or of an optimization tool to converge. In yet another example, the failure may be due to a bug. In another example, the failure may be due to bad scaling of information. In yet another example, the failure may be due to a matrix that is singular or close to singular.

In another example, at least part of the project schedule record may be received from an external device, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth).

In some examples, the project schedule record may comprise one or more tasks, for example of tasks 650. In some cases, the project schedule record may further detail preferred and/required execution details of the tasks, such as devices and/or an entities to perform the tasks. In some cases, the project schedule record may further comprise relations among the tasks. Some examples of relations between two tasks may include a task that must finish before the other task begins, a task that can start only after the other task is completed, a task that must start before the other task begins, a task that can only start after the other task starts, a task that can finish only after the other task starts, a task that must start before the other task can finish, a task that can only finish after the other task is completed, a task that must finish before the other task in complete, and so forth. In some examples, a task may depend on results and/or intermediate results of another task. For example using the results and/or intermediate results as input to the task. In another example, the execution of the task may be controlled based on the results and/or intermediate results (for example, forgoing the performance of the task in response to some results and/or intermediate results, selecting a device to perform the task based on the results and/or intermediate results, modifying parameters and/or hyper-parameters of the task based on the results and/or intermediate results, etc.), and so forth.

In some embodiments, updating the project schedule record (Step 1830) may comprise updating the project schedule record obtained by Step 1820 based on the progress update obtained by Step 1810. In some examples, the updated project schedule record may be stored in memory (such as memory units 210, shared memory modules 410, and so forth) in addition to or instead of the project schedule record obtained by Step 1820. In some examples, the updated project schedule record may be provided to external devices, for example using communication devices (such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth).
In some examples, the progress update may comprise an indication of a completion of a task, and in response Step 1830 may mark the task as completed in the project schedule record and/or logs 660, mark other tasks as ready to be started in the project schedule record and/or cause the other tasks to be started (for example, the other tasks may comprise tasks that can start only after the task of the progress update is completed), signal to some active tasks that they may finish (for example, to active tasks that can finish only after the task of the progress update is completed), and so forth. In some examples, the progress update may comprise an indication of a beginning of a task, and in response Step 1830 may mark the task as started in the project schedule record and/or logs 660, mark other tasks as ready to be started in the project schedule record and/or cause the other tasks to be started (for example, the other tasks may comprise tasks that can start only after the task of the progress update starts), signal to some active tasks that they may finish (for example, to active tasks that can finish only after the task of the progress update starts), and so forth.
In some examples, the progress update may comprise results and/or intermediate results of a task, and in response Step 1830 may cause the results and/or the intermediate results and/or information based on the results and/or information based on the intermediate results to be provided to another task (for example, to be used as input data). In some examples, the progress update may comprise results and/or intermediate results of a task, and Step 1830 may use the results and/or the intermediate results to control the execution of another task (for example, by updating the project schedule record accordingly), for example forgoing the performance of the other task in response to some results and/or the intermediate results, selecting a device to perform the other task based on the results and/or the intermediate results, setting and/or modifying parameters and/or hyper-parameters of the other task based on the results and/or the intermediate results (for example, setting hyper-parameters of a machine learning algorithm associated with the other task), and so forth.
In some examples, the progress update may be related to an action involving a dataset and/or an annotation, such as creating the dataset and/or annotation, modifying the dataset and/or annotation, deleting the dataset and/or annotation, using information from the dataset and/or annotation, and so forth. Further, project schedule record and/or elements of a project schedule record that correspond to said dataset and/or annotation may be selected by Step 1820 and/or updated by Step 1830. For example, an element of a project schedule record may be selected of a plurality of alternative elements of the project schedule record corresponding to different datasets and/or annotations based on the identity of the dataset and/or annotation related to the action, and the selected element may be updated according to the type of the action, properties of the action, the results of the action, and so forth. For example, the action may involve addition of elements to the dataset and/or annotation, and the update of the project schedule record and/or the element of the project schedule record may be based on the number of elements added, the types of added elements, the content of the added elements, and so forth. In another example, the action may involve deletion of elements from the dataset and/or annotation, and the update may be based on the number of elements deleted, the types of deleted elements, the content of the deleted elements, and so forth. In yet another example, the action may involve modifying elements in the dataset and/or annotation, and the update may be based on the number of elements modified, the types of modified elements, the content of the modified elements, the modified information, and so forth. In another example, the action may involve obtaining information from elements in the dataset and/or annotation, and the update may be based on the number of elements accessed, the types of accessed elements, the content of the accessed elements, and so forth.
In some examples, the progress update may be related to an action involving training machine learning algorithm, possibly training a machine learning algorithm using one or more hyper-parameters, for example using data from datasets 610 and/or annotations 620 and/or views 630. Further, a project schedule record and/or elements of a project schedule record that correspond to said machine learning algorithm and/or said hyper-parameters may be selected by Step 1820 and/or updated by Step 1830. For example, an element of a project schedule record may be selected of a plurality of alternative elements of the project schedule record corresponding to different machine learning algorithms and/or different hyper-parameters based on the identity of the machine learning algorithm and/or the values of the hyper-parameters related to the action, and the selected element may be updated according to the type of the action, properties of the action, the result of the action, and so forth. For example, the progress update may comprise intermediate results and/or intermediate status of the training task, for example as obtained by Step 1310, and the update of the of the project schedule record and/or the element of the project schedule record may be based on the intermediate results and/or intermediate status, for example updating the expected run time of the machine learning training task, creating new machine learning training tasks with different hyper-parameters, modifying the hyper-parameters of machine learning training tasks, ending the machine learning training task related to the action (for example, in response to a progress update that indicates a failure to converge of the machine learning training, to a progress update that indicates that the machine learning training task is inferior to another machine learning training task, and so forth), canceling future tasks, and so forth. In another example, the progress update may comprise results of the training task, for example as obtained by Step 1020, and the update of the of the project schedule record and/or the element of the project schedule record may be based on the results, for example creating new machine learning training tasks with different hyper-parameters, modifying the hyper-parameters of machine learning training tasks, canceling future tasks, and so forth.
In some examples, the progress update may be related to an action involving minimizing and/or maximizing an objective function (for example, an objective function based on data from datasets 610 and/or annotations 620 and/or views 630). Further, a project schedule record and/or elements of a project schedule record that correspond to said objective function and/or the optimization method used and/or hyper-parameters of the optimization method used may be selected by Step 1820 and/or updated by Step 1830. For example, an element of a project schedule record may be selected of a plurality of alternative elements of the project schedule record corresponding to different objective functions and/or different optimization methods and/or different hyper-parameters based on the identity of the objective function and/or the optimization method used and/or hyper-parameters related to the action, and the selected element may be updated according to the type of the action, properties of the action, the result of the action, and so forth. For example, the progress update may comprise intermediate results and/or intermediate status of the optimization (such as objective value, iteration number, gradient at the intermediate result, last step size, rate of convergence), and the update of the of the project schedule record and/or the element of the project schedule record may be based on the intermediate results and/or intermediate status, for example updating the expected run time, creating new optimization tasks with different objective functions and/or optimization methods and/or hyper-parameters, modifying the hyper-parameters, ending the task related to the action (for example, in response to a progress update that indicates a failure to converge of the minimization and/or maximization, to a progress update that indicates that the minimization and/or maximization task is inferior to another minimization and/or maximization task, and so forth), canceling future tasks, and so forth.
In some examples, the progress update may comprise results and/or intermediate results related to an action involving some hyper-parameters. Step 1830 may evaluate the results and/or intermediate results, possibly in view of other results and/or intermediate results involving other actions and/or other hyper-parameters. Based on the evaluation, Step 1830 may create new tasks related to other hyper-parameters (for example, in a hyper-parameters search scheme), delete tasks related to other hyper-parameters (for example, in response to concluding that the results and/or intermediate results are satisfying, are a failure, etc.), and so forth.
In some examples, the progress update may comprise indications of failures, and Step 1830 may comprise modifying the project schedule record in response to the failures. Additionally or alternatively, Step 1830 may provide a suggestion to correct the cause to the failure, for example to a user, to a system manager, to an external device, to a different process, and so forth. For example, the failure may be due to a missing and/or incompatible software (for example, missing software license, old software version, etc.), and Step 1830 may modify the project schedule record to use different software, may provide a suggestion to upgrade the software, may provide a suggestion to purchase a software license, may provide a suggestion to install the software, and so forth. In another example, the failure may be due to an incompatible hardware (for example, insufficient memory, missing GPU, etc.), and Step 1830 may modify the project schedule record to use alternative device (for example, choosing the alternative device using process 1200), may modify the project schedule record to use an algorithm and/or hyper-parameters compatible with the available hardware (for example, using process 900), may provide a suggestion to upgrade the hardware, and so forth. In yet another example, the failure may be due to incompatible and/or insufficient permission, and Step 1830 may modify the project schedule record to use alternative resources, may provide suggestions using Step 1650, and so forth. In another example, the failure may be due to insufficient quota, and Step 1830 may modify the project schedule record to use alternative resources, may provide suggestions using Step 1750, and so forth. In yet another example, the failure may be due to missing and/or incompatible and/or insufficient data (for example, dataset with too few examples for a selected machine learning algorithm, dataset with no or insufficient annotations, annotations that are incompatible with a training task, and so forth), and Step 1830 may modify the project schedule record to use alternative datasets and/or annotations, may suggest alternative datasets and/or annotations (for example using Step 1650 and/or Step 1750), and so forth. In another example, the failure may be due to a failure to converge of a machine learning algorithm and/or optimization tool, and Step 1830 may modify the project schedule record and/or provide suggestion to use different machine learning algorithm, different optimization tool, different initialization, different hyper-parameters, and so forth. In yet another example, the failure may be due to a bug, and Step 1830 may modify the project schedule record and/or provide suggestion to use a different software package and/or a different software routine. In another example, the failure may be due to a bad scaling of information, and Step 1830 may modify the project schedule record and/or provide suggestion to use different scaling. In yet another example, the failure may be due to a matrix that is singular or close to singular, and Step 1830 may modify the project schedule record and/or provide suggestion to use different information and/or different method.
In some embodiments, predicting a delay (Step 1840) may comprise analyzing project schedule records to predict delays, for example in response to modification of the project schedule records by Step 1830, periodically, and so forth. For example, project schedule records may comprise a machine learning training task and a corresponding desired finish time for the task, and Step 1840 may predict that the running time of the machine learning training task will cause a change in the finish time (compared to the desired finish time, such as a delay, advance, etc.), for example using estimated processing time obtained using process 1200. In another example, process 1200 may provide a distribution of estimated processing times, and a probability of delay and/or a probability of a delay longer than a selected threshold may be calculated according to the distribution. In yet another example, project schedule records may comprise two tasks, where the start and/or finish of the second task depends on the start and/or finish time of the first task, and Step 1840 may predict a delay in the second task in response to a progress update obtained by Step 1810 that indicates a delay in the first task. In some examples, Step 1840 may determine that the predicted delay is shorter than a selected threshold and/or that the probability of delay is below a selected threshold and/or that the probability of a delay longer than a first select threshold is below a second selected threshold, and in response withhold and/or forgo Step 1850.
In some embodiments, providing an indication (Step 1850) may comprise providing an indication in response to a delay predicted by Step 1840. For example, the indication may be provided to a user, to a system manager, to an external device, to a different process, and so forth. In some examples, the indication may comprise identifying information of the delayed task, a description of the cause to the delay, an estimated length of delay, a suggestion to modify one or more aspects of the project schedule records in response to the delay (for example, to avoid the delay), and so forth. For example, the indication may comprise a suggestion to modify a task by replacing a first machine learning algorithm and/or a first set of hyper-parameters with a second machine learning algorithm and/or a second set of hyper-parameters, for example by selecting machine learning algorithm and/or set of hyper-parameters that is predicted to take shorter processing time. In another example, the indication may comprise a suggestion to replace a usage of a first device with a usage of a second device, for example with a more powerful device that is predicted to finish the task faster. In yet another example, the indication may comprise a suggestion to replace a usage of a first inference model with a second inference model, for example using process 900. In another example, the indication may comprise a suggestion to replace the usage of one dataset with another dataset, replace the usage of a first set of annotations with a second set, and so forth, for example with smaller datasets and/or annotations that are predicted to shorten the processing time.
