Abstract
An online system trains a machine learning model for providing content items to users of the online system. The online system logs actions performed by users and generates user feature vectors based on the logged actions. The online system generates item feature vectors based on information about items from third parties. The machine learning model is trained using the user feature vectors and item feature vectors. The machine learning model determines a likelihood that a target user will acquire a certain item, especially after an update or change has occurred relating to that item. The online system selects content items that the target user is likely to be interested in and is likely to interact with.
