Abstract: A computer system receives a database query to be executed against a database having a database table that stores records associated with keys. The database query specifies a set of conditional expressions that affect which ones of those records are returned. Based on the set of conditional expressions, the computer system derives a set of key ranges. The deriving can include representing the set of conditional expressions as a set of key spaces, performing a set of logical operations on pairs of those key spaces to reduce a number of key spaces in the set of key spaces, and converting the set of key spaces into the set of key ranges after performing the set of logical operations.

Abstract: A machine learning serving infrastructure implementing a method of receiving or detecting an update of container metrics including resource usage and serviced requests per model or per container, processing the container metrics per model or per container to determine recent resource usage and serviced requests per model or per container, and rebalancing distribution of models to a plurality of containers to decrease a detected load imbalance between containers or a stressed container in the plurality of containers.

Abstract: Techniques are disclosed relating to software failover across multiple computing regions. Software entities in a first computing region implement failure recovery routines on an as-needed basis, which can include utilizing code in a recovery API. These software entities can subscribe to receive failure notifications for that region. When an indication of a regional failure is received (e.g., indicating that some specified threshold of servers in the first computing region have failed or are likely to fail), a failure notification can be published. The computing region can then use a list of subscribing software entities to initiate recovery routines for those entities to failover to a different one of the computing regions. In some implementations, software entities can handle failover for dependent components. Thus, when failover is initiated for a particular software product, the product can initiate failover for any constituent components (e.g., services that make up the software product).

Abstract: Embodiments are directed to a training framework for reducing gender bias in a pre-trained language model. To reduce gender bias a gender neutral dataset is generated. Next, parameters of the pre-trained language model are frozen and do not change during a subsequent training phase. As all the pre-trained parameters are frozen, forgetting of information from the original training data is minimized. New parameters are added to the language model. The new parameters may be associated with gender related terms, such as profession names. In a subsequent training phase the new parameters of the language model are trained using a gender neutral dataset.

Abstract: Embodiments are directed to pre-training a transformer model using more parameters for sophisticated patterns (PSP++). The transformer model is divided into a held-out model and a main model. A forward pass and a backward pass are performed on the held-out model, where the forward pass determines self-attention hidden states of the held-out model and the backward pass determines loss of the held-out model. A forward pass on the main model is performed to determine a self-attention hidden states of the main model. The self-attention hidden states of the main model are concatenated with the self-attention hidden states of the held-out model. A backward pass is performed on the main model to determine a loss of the main model. The parameters of the held-out model are updated to reflect the loss of the held-out model and parameters of the main model are updated to reflect the loss of the main model.

Abstract: Methods and systems are provided for automatically determining a need to invoke functionality of a feature of an application while using a primary application and for automatically invoking that functionality without user action. When input information is input into the primary application via a user interface of a user system, it can be received by an application server from a sender process at the user system, and a prefix that occurs before a text string can be identified. The text string that follows the prefix can be extracted by performing a matching analysis against a library of keywords and extracting a matching keyword. The text string comprises extracted text from the input information. The matching keyword can be matched to an entry that is mapped to a command that can be executed to generate an action that automatically invokes the functionality of the feature of the application without user action.

Abstract: Media, methods, and systems are disclosed for documenting synchronous multimedia collaboration sessions in a group-based communication system. A live synchronous multimedia collaboration session is detected. In response to the detecting, a first audio segment is received and transcribed into a first text segment. A collaboration thread associated with the live synchronous multimedia collaboration session is generated. In real time, a first message is posted based on the first transcribed text segment to the collaboration thread associated with the live synchronous multimedia collaboration session. Next, a second audio segment is received and transcribed into a second text segment. Finally, in real time and during the live synchronous multimedia collaboration session, a second message is posted to the collaboration thread based on the second transcribed text segment.

Abstract: Media, methods, and systems are provided for scheduling a scheduled event within a synchronous multimedia collaboration session within a group-based communication system. A selected start time and a selected time duration may be received such that one or more users are added to the synchronous multimedia collaboration session within a channel of the group-based communication system at or near the selected start time. Upon expiration of the selected time duration, the one or more users may be automatically removed from the synchronous multimedia collaboration session to prevent the scheduled event from extending beyond an allocated time.

Abstract: A system performs group testing on a population of items. The group testing identifies items satisfying particular criteria from a population of items, for example, defective items from the population. The group testing may be performed for software or hardware testing, for testing a human population, for training of deep learning applications, and so on. The system trains a machine learning based model, for example, a reinforcement learning based model to evaluate groups. The model may further determine system dynamics that may represent priors of items. An agent treats the population and groups of items being tested as the environment and performs actions, for example, adjusting the groups. The system also performs a non-adaptive strategy based on monte carlo simulation of tests based on a simulation results.

Abstract: Disclosed are methods, apparatus, systems, and computer readable storage media for providing access to a private resource in an enterprise social networking system. One or more servers may receive a request for access to a private resource to be granted to a user from a publisher. The publisher may be configured to publish a message as a feed item to one or more feeds, where the message includes a user identification identifying the user. The user does not have access to the private resource. The feed item may be provided to display in the one or more feeds. Access may be granted to the user via the one or more feeds. In some implementations, access may be granted in response to a user input from the feed item associated with a moderator or owner, the moderator or owner having a privilege to control user access to the private resource.

Abstract: Methods, systems, apparatuses, devices, and computer program products are described. A group-based communication system may support domain and invite management, for example, for a group-based communication channel. A first user may create a channel invite and may add an email address for a second user to the invite. The second user may have multiple accounts in the group-based communication system. The system may determine that the domain of the second user's email address has an organization configured as the primary organization for the domain, and the system may automatically configure the invite to correspond to an account for the second user that is associated with the domain's primary organization. The system may route the invite to the account associated with the primary organization and may send the invite (e.g., a channel invite to the group-based communication channel) to a second user device associated with the second user.

Abstract: Methods, systems, and devices supporting managing a data processing flow are described. A device (e.g., an application server) may host a cloud-based collaboration application, such as an interactive document application. The device may receive an instance of a data processing flow for a flow application based on a first user input to the cloud-based collaboration application. The device may receive the instance of the data processing flow from a source device hosting the flow application. The device may embed the flow application in the cloud-based collaboration application. The device may then receive user inputs to the data processing flow from multiple users collaborating on the same flow in the cloud-based collaboration application. Based on the user inputs, the device may modify the instance of the data processing flow and transmit the modified instance back to the source device to synchronize the data processing flow in the flow application.

Abstract: Disclosed are database systems, computing devices, methods, and computer program products for identifying recurring sequences of user interactions with an application. In some implementations, a server of a database system provides a user interface of the application for display at a computing device. The database system stores data objects identifying a first plurality of user interactions with the application. The server receives information representing a second plurality of user interactions with the application. The server updates the database system to further identify the second user interactions. The server identifies a recurring sequence of user interactions from the first and second user interactions as resulting in a first target state of the application. The server updates the database system to associate the recurring sequence of user interactions with the first target state of the application.

Abstract: The present disclosure is related to virtual spaces, such as channels, of a communication platform. In some cases, a channel may be designated as a private channel, which may permit access to the private channel by only users joined to the channel and may restrict/prevent access by all other users. The present disclosure is related to solutions for changing the private channel to a public channel, which may allow additional user accounts that were not associated with the private channel to discover and/or access the converted channel.

Abstract: Disclosed are systems, apparatus, methods, and computer readable media for suppressing network feed activities using an information feed in an on-demand database service environment. In one embodiment, a message is received, including data indicative of a user action. An entity associated with the user action is identified, where the entity is a type of record stored in a database. A type of the entity is identified. It is determined whether the entity type is a prohibited entity type. When the entity type is not a prohibited entity type, the message data is saved to one or more tables in the database. The tables are configured to store feed items of an information feed capable of being displayed on a device. When the entity type is a prohibited entity type, the saving of the message data, to the one or more tables in the database configured to store the feed items, is prohibited.

Abstract: Techniques are disclosed relating to updating schema information for multi-tenant databases. In some embodiments, a multi-tenant database system stores a standard schema for a database object, where the standard schema is shared by multiple tenants and a tenant-specific schema for the database object. The tenant-specific schema may include one or more tenant-specific custom elements for the database object. The system may enforce a naming scheme in which tenant-specific elements include a predetermined pattern that is not included in object elements of the standard schema. The system may, in response to detecting an update of the standard schema, automatically propagate the update to the tenant schema, while the tenant is online.
