Sparse Non-negative Matrix Factorizations via Alternating Non-negativity-constrained Least Squares (Georgia Institute of Technology, 2006)Many practical pattern recognition problems require non-negativity constraints. For example, pixels in digital images and chemical concentrations in bioinformatics are non-negative. Non-negative matrix factorization (NMF) ...
