Dynamic poisson factorization
WebMoreover, multiple distinct populations may not be well described by a single low-dimensional, linear representation.To tackle these challenges, we develop a clustering method based on a mixture of dynamic Poisson factor analyzers (DPFA) model, with the number of clusters treated as an unknown parameter. WebA new model, named as deep dynamic poisson factorization model, is proposed in this paper for analyzing sequential count vectors. The model based on the Poisson Factor …

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). Typically, the latent factors are assumed to be static and, given these factors, the observed preferences and behaviors of users are assumed to be generated without order. These … Webusers’ dynamic preferences[Liu, 2015]. In addition, Charlin et al. developed a dynamic Poisson factorization model that exploited Kalman filter to model evolving latent embeddings and used Poisson distribution to model the user-item interac-tions[Charlinet al., 2015].
