Web12 de jul. de 2015 · We develop hierarchical Poisson matrix factorization (HPF), a novel method for providing users with high quality recommendations based on implicit feedback, such as views, clicks, or purchases. In contrast to existing recommendation models, HPF has a number of desirable properties. WebHierarchical Poisson factorization (HPF) [1] factorizes user-item consuming by Poisson distributions and solve for optimal matrices by maximizing the log-posteriori. Non-parametric PF [2] also is proposed to control the dimensionality of latent factors automatically. In addition, Johnson [9] proposes logistic matrix WebA Bayesian treatment of the Poisson model, with Gamma conjugate priors on the latent factors, laid the foundation for the more recent hierarchical Poisson fac-torization. Poisson factorization demonstrates more ecient inference and better recommendations than both traditional matrix factorization and its variants that adjust for sparse data. dallas dentistry associates pc
