VALUE-ALIGNED RECOMMENDATIONS

Abstract:

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for ranking items for presentation to a user based on a model that estimates value to the user. One method includes providing value-based training data, the training data including user features, features of corresponding content items presented to users, and respective values of a value variable determined from user behaviors with respect to content items presented to the users; training a scoring model on the training data to generate value-based scores from user content item features; ranking a plurality of candidate content items selected for a first user by a ranking engine, wherein the ranking engine receives respective value-based scores generated by the trained scoring model for the candidate content items and the first user; and providing two or more of the candidate content items for presentation to the first user in an order determined by the ranking.
