Recommender System

We are provided a matrix V of dimensions (number of users, number of movies). This matrix is filled with 0 if the user did not like the movie and one if the user liked it. The rest of the values are NaNs.

In the first step, we use non-negative matrix factorization (NMF) to find two matrices W and H of respective sizes (number of users, K) and (K, number of movies) that minimize the difference between V and WH where K is a small value (< 10). That means we look for W and H such as WH is close to V.

Afterward, we use W and H to cluster the users and can now recommend movies that will be liked by their assigned cluster.

Face and Image Recognition

A facial recognizer to detect faces using a webcam and OpenCV. This project was first extended to simple objects before being extended again to custom objects retraining a pre-trained state-of-the-art TensorFlow model.
