Dynamic poisson factorization
WebCBPF takes recently proposed Bayesian Poisson factorization as its basic unit to model user response to events, social relation, and content text separately. Then it further jointly connects these units by the idea of standard collective matrix factorization model. Moreover, in our model event textual content, organizer, and location ... WebModels for recommender systems use latent factors to explain the preferences and behaviors of users with respect to a set of items (e.g., movies, books, academic papers). …

WebPoisson-based dynamic matrix factorization models are recent advances for modeling dynamic data, such as dPF [16] and DCPF [34] for recommendations. dPF faces the same problem as dynamic PMF since it uses the Gaussian state space. DCPF uses the WebAug 17, 2016 · We propose a novel dynamic PF model: dynamic compound-Poisson factorization (DCPF). DCPF is a novel dynamic probabilistic model that represents the user and item latent factors as independent smoothly-evolving gamma-Markov chains.
