Bayesian Mean-parameterized Nonnegative Binary Matrix Factorization

1 code implementation17 Dec 2018 Alberto Lumbreras, Louis Filstroff, Cédric Févotte

In some cases, the analysis of binary matrices can be tackled with nonnegative matrix factorization (NMF), where the observed data matrix is approximated by the product of two smaller nonnegative matrices.

no code implementations ICML 2018 Louis Filstroff, Alberto Lumbreras, Cédric Févotte

We present novel understandings of the Gamma-Poisson (GaP) model, a probabilistic matrix factorization model for count data.
