Zhong, M., Girolami, M.: Reversible jump mcmc for non-negative matrix factorization. We find that the probabilistic sparse NMF is able to automatically learn the level of sparsity and find that the existing probabilistic NMF as well as the proposed probabilistic sparse NMF prunes inactive components and thereby automatically learns a suitable number of components. In this paper, we propose a probabilistic sparse non-negative matrix factorization model that extends a recently proposed variational Bayesian non-negative matrix factorization model to explicitly account for sparsity. We further find that accounting for sparsity can provide more part based representations but for the probabilistic modeling the choice of priors and how sparsity is imposed can have a strong influence on the extracted representations. Rather than when you have a larger not sparse matrix with a lot of zeros, you can end up eating a lot of memory. The objective function is: Ask Question Asked 2 years, 10 months ago. Sci.
