  • Publication number: 20220327327
    Abstract: An approach is provided in which the approach receives scored records that include a selected scored record comprising a first fairness group attribute, a first prediction, and a first confidence value corresponding to the first prediction. The approach perturbs the selected scored record to a second fairness group attribute in response to determining that the first confidence value is below a confidence threshold. The approach scores the perturbed record to generate a second prediction and a second confidence value corresponding to the second prediction. The approach modifies the selected scored record by changing the first prediction to the second prediction in response to determining that the second prediction is different from the first prediction and that the second confidence value is higher than the confidence threshold.

  • Publication number: 20220329460
    Abstract: An apparatus, system, method, and computer-readable recording media perform smart control in a wireless network, which includes a plurality of wireless devices. Configuration parameters are obtained to set one wireless device as an active master device in the wireless network. The active master device receives updates in the configuration parameters and learned station (STA) information, and periodically transmits the updates to the configuration parameters and the learned STA information to the other wireless devices in the wireless network. Any one of the other wireless devices in the wireless network can use the updates to the configuration parameters and the learned STA information to be set as a new active master device in the wireless network when the active master device becomes out of network.

  • Publication number: 20220314167
    Abstract: A high salinity feed water such as seawater is treated to produce a reverse osmosis (RO) concentrate and an RO permeate. Optionally, some or all of the RO concentrate may be filtered to produce a nanofiltration (NF) permeate. Optionally, some feed water can also be filtered to produce NF permeate without first being concentrated by RO treatment. The NF permeate, or a blend of the RO permeate and NF permeate, may be used to produce a product water for injection into an oil-bearing reservoir to enhance oil recovery. Optionally, the product water may have salinity greater than the feedwater, or at least 30 g/L. The product water may have hardness of less than 20 mg/L.

  • Publication number: 20220180222
    Abstract: A system and related method score a fairness of an outcome model. The method comprises receiving a set of original transaction records (OTRs), and selecting an OTR subset of the OTRs according to a subset selection criteria in order to reduce a number of OTRs to send to outcome model. For each OTR in the subset a perturbed transaction record (PTR) is created based on the OTR that includes changing at least one attribute in the PTR from the OTR, sending the OTR and the PTR to the outcome model, receiving an OTR outcome and a PTR outcome from the outcome model, and determining a record bias score for the OTR outcome and the PTR outcome respectively that indicates bias in the respective outcome. The OTR and the PTR bias score are stored in a bias determination system (BDS) database.

  • Publication number: 20220164606
    Abstract: A machine learning model data quality improvement detection tool is provided for identifying an accurate reference group and an accurate monitored group of a machine learning model. The tool monitors a behavior of the machine learning model for a predetermined time frame. The tool compares a determined fairness metric a pre-defined fairness threshold. Responsive to the fairness metric failing to meet the pre-defined fairness threshold, the tool modifies the monitored group to include a first portion of the reference group. The tool compares a newly determined fairness metric to the pre-defined fairness threshold. Responsive to the newly determined fairness metric meeting the pre-defined fairness threshold, the tool identifies the modified monitored group including the first portion of the user-defined reference group as a new monitored group and the modified reference group without the first portion of the user-defined reference group as a new reference group.

  • Patent number: 11341135
    Abstract: An approach is provided for optimizing data fetching. A query employing a method to fetch data from a JSON document is received. An amount of time required to execute the query and a number of nested layers in a traversal of the JSON document required to fetch the data are determined. Based on the amount of time and the number of nested layers, a cost associated with an execution of the query is calculated. The cost is determined to exceed a threshold value. Responsive to the determination that the cost exceeds the threshold value and using historical query patterns and historical query execution times, a schema of the JSON document is re-designed. The data is fetched from the JSON document using the re-designed schema.

  • Publication number: 20220147852
    Abstract: A computer device receives historical prediction data, where the historical prediction data includes historical data and corresponding predictions generated for the historical data by a regression machine learning model. The computing device identifies undesired predictions in the historical prediction data based, at least in part, on a perturbation analysis, where the perturbation analysis includes modifying an attribute of the historical data and using the regression machine learning model to generate predictions for the historical data with the modified attribute. The computing device trains a binary classification model to classify predictions as undesired, using the historical prediction data and the identified undesired predictions as training data. The computing device generates a prediction for a new data entry utilizing the regression machine learning model and the binary classification model.

  • Publication number: 20220012168
    Abstract: Embodiments provide systems, methods, and computer-readable storage media for automated and objective testing of applications or processes. Graphical representations of the application may be analyzed to derive attribute data and identify flows (e.g., possible processing paths that may be accessed during utilization of the application by a user). Test cases may be automatically generated based on the attribute data and the identified flows. Additionally, testing scripts for testing the portions of the application corresponding to each identified flow may be generated using machine learning logic. Once generated, the testing scripts may be executed against the application to test different portions of the application functionality (or processes). Execution of the testing scripts may be monitored to generate feedback used to train the machine learning logic. Reports may be generated based on the monitoring and provided to users to enable the users to resolve any errors encountered during the testing.
