DCPF is a novel dynamic probabilistic model that represents the user and item latent factors as independent smoothly-evolving gamma-Markov chains. There has been a recent dynamic extension attempt for PF replacing the gamma priors …
WebApr 8, 2024 · This article presents a Poisson common factor model with an overdispersion factor to predict some multiple populations’ mortality rates. We use Bayesian data analysis and an extension of the Hamiltonian Monte Carlo sampler to compute the estimation of the model parameters and mortality rates prediction. We apply the proposed model to the … 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). …
