We conduct experiments on several data combination and report significant improvements over state-of-the-art transfer-based models for collaborative filtering. Matrix factorization is the breaking down of one matrix into a product of multiple matrices. It’s extremely well studied in mathematics, and it’s highly useful. There are many different ways to factor matrices, but singular value decomposition is particularly useful for making recommendations.

Nonnegative Matrix Factorization with Side Information for Time Series Recovery and Prediction, with J-M Azaïs & Y. Goude & G. Hébrail & J. Mei, IEEE Transactions on Knowledge and Data Engineering, Volume 31, Issue 3, March 1, Pages 493-506, 2019. Matrix has powerful and comprehensive checks. It can check almost all cheats that can affect the fairness of the server, such as KillAura or Speed, all of which are done automatically. You can also customize many parameters in the configuration file, or customize the penalty command.matrix factorization methods [24]–[26] have been proposed. They depict the low-rank structure of a matrix by factorizing it into the product of two smaller matrices and avoid computing SVD, thus are more efficient. Besides, by directly restricting the rank of the estimation, the low-rank factorization methods
