Abstract: An online system receives a list of third party user identifiers from a third party attribution system, each associated with one or more user action events by each of a set of users across multiple content providers. The online system determining if it has its own user identifiers that match to at least a subset of the received third party user identifiers. The online system determines relevant impressions corresponding to the matching online system user identifiers, and sends them to the third party attribution system along with an associated subset of the third party user identifiers.

Abstract: An online system receives a request for a video to be presented by the online system to a target user. The online system determines whether to insert secondary content into the video. For such a determination, the online system identifies a position in the video for inserting secondary content. Further, the online system determines a loss score and a gain score. The loss score measures a loss of interaction by the target user if the secondary content were inserted. The gain score includes a monetary compensation to be received by the online system for inserting the secondary content at the identified position. The online system compares the loss score and the gain score. Based on the gain score offsetting the loss score, the online systems modifies the video by inserting the secondary content at the identified position and provides the modified video for display to the target user.

Abstract: Disclosed is an online system that infers interests of unresolved users for whom the interests are not known. The online system determines certain features about the unresolved users, but does not have certain information about the users themselves (e.g., their interests), so instead infers these attributes based on the features of the user. The online system provides the features as input to a classifier trained to predict a particular interest, and the classifier outputs a prediction of whether the user has the corresponding interest. In one embodiment, the online system trains a classifier for various interest values by forming training sets for the interests using the features for users who are logged into the online system and hence have known interests.

Abstract: A system includes multiple client devices that are capable of capturing and displaying video data, in which at least two of the client devices have different amounts of processing power. A connection is established at a client device having more processing power to a client device having less processing power. The client device having more processing power receives video data captured by the client device having less processing power as well as metadata associated with the video data via the connection as the video data are being captured by the client device having less processing power. The client device having more processing power processes the video data based on the metadata associated with the video data within a duration of the connection, thereby enhancing a quality of the video data. The processed video data are then displayed at the client device having more processing power.
