Sparse encoding for more-interpretable feature-selecting representations in probabilistic matrix factorization

ICLR 2021poster

Dimensionality reduction methods for count data are critical to a wide range of applications in medical informatics and other fields where model interpretability is paramount. For such data, hierarchical Poisson matrix factorization (HPF) and other sparse probabilistic non-negative matrix factorizat…
