WebHierarchical Poisson factorization (HPF) (Gopalan et al. 2014; Gopalan, Hofman, and Blei 2015) models the user-item consumption by assuming each entry to be a factorized Poisson. Poisson factorization has several merits: down-weighting the effect of matrix sparsity, model-ing the long-tail of users and items, and fast inference. 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.
