Informed Weighted Non-Negative Matrix Factorization Using αβ-Divergence Applied to Source Apportionment

Informed Weighted Non-Negative Matrix Factorization Using αβ-Divergence Applied to Source Apportionment

In this paper, we propose informed weighted non-negative matrix factorization (NMF) methods using an α β -divergence cost function. The available information comes from the exact knowledge/boundedness of some components of the factorization—which are used to struc...
