WebPoisson factorization is a probabilistic model of users and items for recommendation systems, where the so-called implicit consumer data is modeled by a factorized Poisson distribution. There are many variants of Poisson factorization methods who show state-of-the-art performance on real-world recommendation tasks. Webexamples that motivate this work. The Hierarchical Dirichlet Process (HDP) HMM [1, 14] relaxes the as-sumption of a ﬁxed, ﬁnite number of states, instead positing a countably inﬁnite number of latent states and a random transition kernel where transitions to a ﬁnite number of states account for all but a tiny frac-tion of the ...
