EPFL ML Recommender System

For this choice of project task, you are supposed to predict good recommendations, e.g. of movies to users. We have acquired ratings of 10000 users for 1000 different items (think of movies). All ratings are integer values between 1 and 5 stars. No additional information is available on the movies or users.

All information of the task and some baselines are provided in Exercise 10

Please see also detailed instructions on the course github.

Evaluation criteria
