On affine non-negative matrix factorization | Hans Laurberg, Lars Kai Hansen
| | Abstract | We generalize the non-negative matrix factorization (NMF) generative model to incorporate
an explicit offset. Multiplicative estimation algorithms are provided for the resulting sparse
affine NMF model. We show that the affine model
has improved uniqueness properties and leads to more accurate identification of mixing and sources. | | Type | Conference paper [With referee] | | Conference | ICASSP 2007, Hawaii, USA | | Year | 2007 | | Publisher | IEEE | | Electronic version(s) | [pdf] | | BibTeX data | [bibtex] | | IMM Group(s) | Intelligent Signal Processing |
