Publisher summary· verbatim

arXiv:2601.05845v2 Announce Type: replace Abstract: Poisson non-negative matrix factorization (NMF) is a widely used method to find interpretable "parts-based" decompositions of count data. While many variants of Poisson NMF exist, existing methods assume that the "parts" in the decomposition combin
