Comments I've been working on building a content recommender in TensorFlow using matrix factorization, following the approach described in the article Matrix Factorization Techniques for Recommender Systems (MFTRS). The factorization splits the matrix into row factors and column factors that are essentially user and item embeddings. As we will see, these techniques are really easy to implement in TensorFlow, and the resulting code is very flexible and easily allows modifications and improvements. You can take this even further by learning other matrix factorization techniques such as Funk MF, SVD++, Asymmetric SVD, Hybrid MF, and Deep-Learning MF or k-Nearest Neighbours approaches.
