(Matrix Factorizations and Recommender Systems)
Goals. The goal of this exercise is to
• Build a recommender system.
• Learn to evaluate its performance.
• Implement and understand matrix factorization using SGD.
• Implement and understand the alternating least-squares (ALS) algorithm.
Setup, data and sample code. Obtain the folder labs/ex13 of the course github repository
