  • Multi-stage filtering for recommended user connections on online social networks
    Patent number: 10313456
    Abstract: In one embodiment, a method includes identifying a first set of candidate-users. Each candidate-user corresponds to a second user within a threshold degree of separation of a first user within a social graph. The method includes filtering, using a first-stage filtering model, the first set of candidate-users to generate a second set of candidate-users using edge-features. The method includes filtering, using a second-stage filtering model, the second set of candidate-users to generate a third-set of candidate-users using the edge-features and user-features. The method includes ranking, using a user-engagement model, the third set of candidate-users using a feature superset based on a probability of the first user connecting with the respective candidate-user. The method includes sending, to a client system of the first user, instructions for generating a suggested-friends interface for display.
