Global Minimization of the Projective Nonnegative Matrix Factorization

摘要

The Nonnegative Matrix Factorization (NMF) is a widely used method in approximating high dimensional data. All the NMF type methods find only the local minimizers. In this paper, we use filled function method to find the global minimizer of the Projective Nonnegative Matrix Factorization optimal problem.
