Our goal is to be able to predict ratings for movies a user has not yet watched. along with the 1m dataset. We start the journey with the important concept in recommender systems—collaborative filtering (CF), which was first coined by the Tapestry system [Goldberg et al., 1992], referring to “people collaborate to help one another perform the filtering process in order to handle the large amounts of email and messages posted to newsgroups”. All selected users had rated at least 20 movies. In addition, the timestamp of each user-movie rating is provided, which allows creating sequences of movie ratings for each user, as expected by the BST model.
