Primal-Dual Algorithms for Non-negative Matrix Factorization with the Kullback-Leibler Divergence

4 Dec 2014Felipe YanezFrancis Bach

Non-negative matrix factorization (NMF) approximates a given matrix as a product of two non-negative matrices. Multiplicative algorithms deliver reliable results, but they show slow convergence for high-dimensional data and may be stuck away from local minima... (read more)
