Apr 29, 2019 · To build our first collaborative filtering model, we need to take care of a few things first. This model will learn embeddings for users and items, which it will then use to predict ratings. In the latent space, the recommender system predicts a personalized ranking over a set of items for each individual user with the similarities among the users and items. Collaborative filtering algorithms usually perform better than content-based methods. May 24, 2020 · Keras documentation, hosted live at keras.
