Primary language: Python
Description: Optimization in RegularizedΝon-negative Μatrix Factorization. A feature engineering algorithm in multivariate analysis and linear algebra where a matrix Χ is factorized into (usually) two matrices W and H (i call it C), with the property that all three matrices have no negative elements.Also the factorization works better for sparse data than PCA and better interpretation.
