A New Family of Poisson Non-negative Matrix Factorization Methods Using the Shifted Log Link
Eric Weine, Peter Carbonetto, Rafael A. Irizarry +1
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,…
