Abstract: In one embodiment, a method includes receiving, from a device via a wireless signal, a request to access a WLAN of a router, the request including a device identifier. The provisioning agent may be within wireless ranges of the device and of the router. The provisioning agent may request, from an authentication server, a password for the device. The password may be uniquely generated by the authentication server for the device. The provisioning agent may receive the password from the authentication server. The provisioning agent may send, to the router, the password and the device identifier. The provisioning agent may receive, from the router, an indication that the router has verified the password with the authentication server. The router may store the device identifier in association with the password. The provisioning agent may send, to the device, the password. The password may authenticate the device to the router.

Abstract: Systems, methods, and non-transitory computer-readable media can determine that a broadcaster of a first live content stream has identified at least one user of a social networking system to join as co-broadcaster. A merged live content stream is published through the social networking system, the merged live content stream including the first live content stream of the broadcaster and a second live content stream associated with the at least one identified user. At least one notification is sent to one or more other users of the social networking system. The notification informs the one or more other users about the merged live content stream.

Abstract: Systems, methods, and non-transitory computer-readable media can identify a set of videos. One or more overlapping portions in the set of videos are automatically identified. A stitched media content item is automatically generated based on the one or more overlapping portions and at least a subset of the set of videos.

Abstract: A system comprises a processor and a plurality of memory units. The processor is coupled to each of the plurality of memory units by a plurality of network connections. The processor includes a plurality of processing elements arranged in a two-dimensional array and a corresponding two-dimensional communication network communicatively connecting each of the plurality of processing elements to other processing elements on same axes of the two-dimensional array. Each processing element that is located along a diagonal of the two-dimensional array is configured as a request broadcasting master for a respective group of processing elements located along a same axis of the two-dimensional array.

Abstract: Systems, methods, and non-transitory computer-readable media can receive, from a client computing device, a request for a first portion of a content item. The first portion of the content item is determined based on a likelihood of consumption value associated with the content item. The first portion of the content item is transmitted to the client computing device. The first portion of the content item is prefetched by the client computing device.

Abstract: A database search method combines SQL command, complex event processing, and keyword search. Event data records may be collected based on the events specified in a query. A complex event processing analysis is used to determine the records that meet the correct sequence of events. The keyword search is used to filter user data records that have the attributes specified in the query. A SQL command may be used to further analyze or group the data records found. One or more metrics of the filtered results are presented as the result of the query. To run a new query efficiently, user identifiers are distributed using hashes. Adaptive sampling is used to determine whether the search result is within a desired margin of error. An efficient search for a specific condition is performed using a pace computation that jumps into a location of user data records that have the attributes.

Abstract: Techniques are described for generating content to be shared between users. For example, user interfaces are described that include features and/or mode controls for generating content to be shared between users. Additionally, the described techniques include determining content shared between users (e.g., previously distributed content) based on a selection of a second user account, and generating customized content which may be specific to an event that includes the shared content.

Abstract: When a user sees a content item presented by a social networking system, the user may select an option to save the content item. The saved content item may be reinserted in a newsfeed presented to the user, integrated into collections, archived, used for notifications to the user, or otherwise subsequently presented to the user. A plug-in may be used to save content items accessed through websites external to the social networking system. As privacy settings associated with a saved content item are modified, the modified privacy settings are applied to the saved content item, which may prevent the user saving the content item from subsequently viewing the saved content item.

Abstract: The disclosed computer-implemented method may include (1) receiving, at a hardware accelerator that supports an ANN, an activation data set that is to undergo a convolution operation via a filter kernel of the ANN, (2) receiving, at the hardware accelerator, an argument indicating that the filter kernel exceeds at least one boundary of the activation data set when slid across a certain position during the convolution operation, (3) determining, based at least in part on the argument, that the hardware accelerator is to generate padding data at the boundary of the activation data set in connection with the certain position of the filter kernel, and then (4) performing, at the hardware accelerator, the convolution operation by processing a portion of the activation data set and the padding data when the filter kernel slides across the certain position. Various other systems and methods are also disclosed.

Abstract: In one embodiment, a method includes receiving a user query from a client system associated with a first user, executing tasks via agents which return responses, each response comprising information items, analyzing the responses to determine slots, each slot corresponding to one of the information items, determining compositional sub-goals for each response, wherein each compositional sub-goal indicates a semantic-intent of the respective response, generating compositional fragments by a compositional natural-language generation (NLG) model, each compositional fragment comprising a partial natural-language response, determining a top-level compositional goal, generating a communication content by the compositional NLG model, wherein the communication content comprises a complete natural-language response to the user query, and wherein the complete natural-language response is based on the partial natural-language responses of the compositional fragments, and sending instructions for presenting the communication content to the client system.
