In zhilongjia/DNMF: Discriminant Non-Negative Matrix Factorization

Discriminant Non-Negative Matrix Factorization

Discriminant Non-Negative Matrix Factorization is to extend the Non-negative Matrix Factorization algorithm in order to extract features that enforce not only the spatial locality, but also the separability between classes in a discriminant manner. Two kinds of Discriminant Non-Negative Matrix Factorization were implemented so far.
