Abstract: In one embodiment, a controller of a multi-hop wireless network may access an interference map indicating interference among network nodes, each network node comprising sectors that each comprise an array of beamforming antennae. The controller may identify desired links between network nodes, each desired link being associated with a transmitting (TX) beamforming weight variable and a receiving (RX) beamforming weight variable. The controller may generate a factor-graph representation of the multi-hop wireless network comprising a first and second set of vertices, wherein the first set of vertices are variable nodes representing pairs of beamforming weight variables associated with identified desired links, and the second set of vertices are function nodes representing capacity equations associated with identified desired links.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a plurality of candidate entities for recommendation to a user of a social networking system. A predicted activity objective value model configured to calculate activity stores for candidate entities is established. The activity score is indicative of the probability of future activity on the social networking system by a candidate entity. A first activity score is determined for each of the plurality of candidate entities based on the predicted activity object value model and a first set of feature values. A second activity score is determined for each of the plurality of candidate entities based on the predicted activity object value model and a second set of feature values that is different from the first set of feature values. A first entity is selected of the plurality of candidate entities based on the first and second activity scores.

The subset can be dynamically presented based on the set of declarative instructions. The subset can be presented during the playback of the soundtrack and can be presented to represent video content.

Abstract: Users of a social networking system are assigned to households using prediction models that rely, in part, on user profile information and social graph data. Information about users may be received by a social networking system through various channels (e.g., declared/profile information, user history, IP addresses, Global Positioning System (GPS) data from check-in events and/or continuously provided by mobile devices, external household information, and/or social information). Scoring models may use statistical analysis of the received user information to predict household membership for users. User attributes, such as previous names, date of birth, social graph data, locations, life events, and check-ins, may be factors in generating confidence scores of predicted household memberships. Weighted scoring models may use machine learning methods for measuring the accuracy of the household membership prediction.

Abstract: Exemplary embodiments relate to improvements in digital assistants incorporating personalization based on social network data. Various aspects of the agent, such as the agent's voice, language style, and avatar may be personalized. Personalization may be applied to components of an agent's architecture (e.g., the virtual agent's language model, natural language generator, voice generation component, etc.). Moreover, by interfacing with the social network's social graph, the agent may be provided with information useful to performing certain tasks (e.g., a calendar for scheduling, food preferences for ordering tasks, etc.). An agent may be provided (and personalized) for a single user, or a group of users (e.g., a family). The agent can be personalized to anyone, which may allow (e.g.) for the agent to represent a celebrity or a person who is not currently available in interactions with others. Different agents can talk to each other, e.g. for purposes of scheduling meetings.

The method also includes aggregating one or more of the notifications based on the type of notification; determining a sending time to send the aggregated notifications based at least in part on determining that a pre-determined amount of time that has elapsed from a receipt time of a most recent one of the aggregated notifications; and sending the aggregated notifications to the user based on the sending time.

Abstract: Embodiments include one or more client devices accessible by users, an online system, and one or more partner systems such that the online system is able to identify a user of the online system across different devices and browsers based on the user activity that occurs external to the online system. A user performs user actions (e.g. purchase a product) on a web page of a partner system and may provide personally identifiable information (PII) to the partner system. The partner system provides the hashed PII and user actions performed by the user to the online system. The online system identifies a user profile on the online system by matching personal information in the user profile to the hashed PII. The online system generates a confidence score indicating a likelihood that the identified user of the online system is the individual that performed the external user action.
