In this repository you can find Matrix and Metric Factorizations implemented based on these two papers:
- Y. Koren, R. Bell and C. Volinsky, "Matrix Factorization Techniques for Recommender Systems," in Computer, vol. 42, no. 8, pp. 30-37, Aug. 2009.
- Zhang, Shuai & Yao, Lina & Tay, Yi & Xu, Xiwei & Zhang, Xiang & Zhu, Liming. (2018). Metric Factorization: Recommendation beyond Matrix Factorization.
Dataset used is: MovieLens 100K
Please note, these two implementations are offered without hyperparameter tuning and are prone to some noob TensorFlow mistakes.
