Intuition behind Matrix Factorization
A recommendation engine is a subcategory of machine learning which aims to provide a rating for some user or item. Matrix factorization falls under the category of collaborative filtering in recommendation systems. Intuitively, collaborative filtering aims to identify items that a user A would like based on the interactions…
