Abstract: A method and apparatus for populating content items into a feed is provided. The feed comprises a sequence of content item ordered in such a way as to maximize a number of content items displayed to a user by virtue of the user scrolling down through the feed. The content items are each associated with a click-through rate, an indication of a number of times the content has been displayed to users, an indication of a number of times that the users have scrolled to a next item in the feed after the item was displayed, and a height of the content item. These values are used to train a behavioral model and then used by the behavioral model to layout the content items in a feed rendered at a user device.

Abstract: This disclosure relates to systems and methods for managing multiple messages. In one example, a method includes determining a message transmission frequency threshold for a member of an online social networking service using responses from the member; receiving a message that is to be transmitted to the member; storing the message, without transmitting the message to the member, in a digest of messages for the member; and transmitting the digest to the member in response to a send score for the digest exceeding a send score threshold, the send score calculated using the number of messages in the digest.

Abstract: The disclosed embodiments provide a system for improving long-term engagement with content feeds. During operation, the system obtains a factor associated with a change in a level of engagement with a content feed. Next, the system uses the factor to modulate a feed composition of the content feed for a first set of users. The system then verifies an effect of the factor on the level of engagement by comparing a first level of engagement of the first set of the users with the content feed with a second level of engagement of a second set of users with the content feed. Finally, the system uses the first and second levels of engagement with the content feed to select a value associated with the factor for use in modulating a subsequent feed composition of the content feed.

Abstract: In an example, first and second machine learned models corresponding to a particular context of a social networking service are obtained, the first machine learned model trained via a first machine learning algorithm to output an indication of importance of a social networking profile field to obtaining results in the particular context, and the second machine learned model trained via a second machine learning algorithm to output a propensity of the user to edit a social networking profile field if requested. One or more missing fields in a social networking profile for the user are identified. For each of one or more of the one or more missing fields, the field and an identification of the user are passed through the first and second machine learned models, and outputs of the first and second machine learned models are combined to identify one or more top missing profile fields.

Abstract: A machine may be configured to blend connection recommendation streams. For example, the machine, based on a member identifier of a member of a SNS, accesses a list of other members of the SNS and a list of guests (e.g., non-members). The machine identifies a member probability value representing a likelihood of the member inviting another member to connect via the social graph of the member, and identifies a guest probability value representing a likelihood of the member inviting a guest to connect via the social graph. The machine generates a blended list of other members and guests based on the member probability values, the guest probability values, and a coefficient value selected to control a presence of a type of connections in the blended list. The machine generates recommendations for the member to invite people included in the blended list to connect with the member via the social graph.
