摘要

In this paper we aim at assessing the potential of Binary Matrix Factorization (BMF) in the implementation of recommendation systems, by analyzing a Netflix dataset. In particular, we study the explanatory power and the prediction capability of a particular BMF algorithm based on a post non-linear mixture model, namely the Post NonLinear Penalty Function (PNL-PF) algorithm. Unlike the majority of BMF methods, PNL-PF is capable of efficiently handling the difficult case of correlated rank-1 binary terms. We show that BMF represents an interesting alternative to classical matrix factorization methods in terms of explanatory power and prediction capability.
