We propose a categorical matrix factorization method to infer latent diseases from electronic health records data. WebThe model is similar to Hierarchical Poisson Factorization, but uses regularization instead of a bayesian hierarchical structure, and is fit through gradient-based methods instead of coordinate ascent. It tries to approximate a sparse matrix of counts as a product of two lower-dimensional matrices in a way that maximizes Poisson likelihood - i.e.: Web3.2 Hierarchical Poisson Factorization Hierarchical Poisson factorization[Gopalanet al., 2013] is a probabilistic collaborative ltering recommendation model for users' ratings.
