%description
Discriminant Non-Negative Matrix Factorization aims 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. It refers to three article,
Zafeiriou, Stefanos, et al. "Exploiting discriminant information in
nonnegative matrix factorization with application to frontal face
verification." Neural Networks, IEEE Transactions on 17.3 (2006): 683-695.

the extraction of subtle emotional differences in speech." Cognitive
