An Empirical Comparison of Sampling Quality Metrics: A Case Study for Bayesian Nonnegative Matrix Factorization
Arjumand Masood, Weiwei Pan, Finale Doshi-Velez
In this work, we empirically explore the question: how can we assess the quality of samples from some target distribution? We assume that the samples are provided by some valid Mon…

A Characterization of the Non-Uniqueness of Nonnegative Matrix Factorizations
W. Pan, F. Doshi-Velez
Nonnegative matrix factorization (NMF) is a popular dimension reduction technique that produces interpretable decomposition of the data into parts. However, this decompostion is no…
