Abstract: A tracking sensor integration system presented herein collects sensor data obtained for each time frame by a plurality of sensors attached to a wearable garment placed on a user's hand. A controller coupled to the tracking sensor integration system calculates a measurement gain based at least in part on collected sensor data, and determines prediction for a pose of the user's hand for the current time frame using the collected sensor data and a plurality of estimation parameters for the current time frame. The controller then updates the estimation parameters for the current time frame, based in part on the measurement gain and the prediction for the pose of the user's hand. The controller determines an estimated pose for the user's hand, based in part on the updated estimation parameters and the collected sensor data.

Abstract: An online system receives one or more aggregation rules associated with a third party system that determine online system users' eligibility for receiving content items provided by the third party system using the online system users' behavior. When an online system user performs actions related to content provided by the third party system via a client device, events describing the actions are generated and communicated from the client device to the online system. The online system evaluates a user's eligibility when a user performs an action by applying an aggregation rule to an event corresponding to the user's action and other events associated with the user corresponding to the user's previous actions. The online system may re-evaluate a user's eligibility at a later time if the user is determined to be ineligible. The online system provides content items to eligible users for presentation.

Abstract: The present disclosure describes methods and systems for handling personal identifiable information. In some implementations, the information is collected during the authentication of identification (ID) documents. The system includes a one-way hashing function that converts unique personal identifiable information into a unique digest. The system can store the digest without having to store the personal identifiable information. Because the hashing function generates the same digest when given the same input, the digests can be used as anonymized identifiers in place of the personal identifiable information.

Abstract: An augmented reality (AR) includes a depth camera assembly (DCA) to capture images of various depth zones of scenes of a local area. The DCA can focus on specific ranges in a scene, important aspects, and/or regions of interest. The DCA generates image data of the local area such that the image includes information pertaining to a single depth zone. The captured image is specific to the single depth zone and is representative of objects within the single depth zone. The DCA uses the generated image data for the depth zones to generate augmented or partially-augmented images that include depth information for the objects in the local area.

Abstract: A shared communication channel allows for the transmitting and receiving audio content between multiple users. Each user is associated with a headset configured to transmit and receive audio data to and from headsets of other users. After the headset of a first user receives audio data corresponding to a second user, the headset spatializes the audio data based upon the relative positions of the first and second users such that when the audio data is presented to the first user, the sounds of the audio data appear to originate at a location corresponding to the second user. The headset reinforces the audio data based upon a deviation between the location of the second user and a gaze direction of the first user, allowing for the first user to more clearly hear audio data from other users that they are paying attention to.

Abstract: News feed stories are ranked so that new stories appear above previously viewed stories for users of a social networking system. Top news stories are selected by the social networking system based on a ranking algorithm that incorporates an analysis of affinities for interests, users, and entities in the social networking system based on user interactions. Other new stories are provided after the top new stories in a chronological order. For each user of the social networking system, a view state is recorded that includes the order of news feed stories provided to users. Based on the view state and received user input, the social networking system may determine whether to provide new news feed stories to a viewing user.

Abstract: An online system customizes content items to be displayed on electronic displays. The electronic displays may be located at a venue with a large amount of foot traffic from users such as a park, airport, restaurant, shopping center, or airport. The system receives information from an electronic display describing users in vicinity of, or interacting with, the electronic display. For instance, the electronic display receives information from client devices of the users or by using sensors such as a camera that captures images of the users. Additionally, the system may receive interaction data generated by a touchscreen device of the electronic display. Based on the received information, the online system can select content items that are customized based on the interests of the users. The online system can also provide customized content items for display on a user's client device based on the user's interaction with an electronic display.

Abstract: A location query engine in a social networking system provides users with a subset of candidate locations based on location query received from a user. The social networking system identifies candidate locations from stored location data that has one or more attributes matching at least one attribute of the location query. The candidate locations are ranked based on social data determined from a user profile associated with the user, and the subset of candidate locations is selected from the ranking and provided to the user. Examples of social data used for ranking the candidate locations include locations associated with other users connected to the user, locations associated with objects connected to the user and locations previously associated with the user.

Abstract: To generate an embedding model for entities in an online system, a first set of partitions is generated. Each partition of the first set of partitions includes a subset of entities of the online system. Each partition of at least a subset of partitions of the first set of partitions is assigned to embedding workers. Each of the embedding worker determines embedding vectors for each entity in the partition assigned to the embedding worker. A second set of partitions is generated. Each partition of at least a subset of partitions of the second set of partitions are assigned to embedding workers. Each embedding worker retrieves embedding vectors for the entities in the partition assigned to embedding worker, and determines updated embedding vectors for each of the entities based on the retrieved embedding vectors and information about interaction between the entities.

Abstract: Ion implantation is carried out into a GaN layer of mLEDs to partially or fully convert one or more regions of the crystalline GaN layer to amorphous GaN. As a result, the GaN layer through which light rays propagate have non-uniform refractive indexes that modify propagation paths of some light rays. Ions can be implanted in a region around an active region that emits light to function as an optical waveguide. The ion implanted regions direct light rays that propagate along predetermined directions into predetermined propagation paths thereby to modify the angle of incidence of these light rays. As such, the light extraction efficiency of the mLEDs is increased.

Abstract: An online system identifies an additional feature to evaluate for inclusion in a machine learned model. The additional feature is based on characteristics of one or more dimensions of information maintained by the online system. To generate data for evaluating the additional feature, the online system generates various partitions of stored data, where each partition includes characteristics associated with one or more dimensions on which the additional feature is based. Using values of characteristics in a partition, the online system generates values for the additional feature and includes the values of the additional feature in the partition. Values for the additional feature are generated for various partitions based on the values of characteristics in each partition. The online system combines multiple partitions that include values for the additional feature to generate a training set for evaluating a machine learned model including the additional feature.
