Title: On GEM diffusive mixtures
Author(s): Ramses Mena* and Luis Gutierrez
Companies: Universidad Nacional Autónoma de México and Universidad de Chile
Keywords: Bayesian nonparametrics ; Dependent process ; mixture model ; diffusion process ; measure-valued process

We present and discuss the class of dependent mixture models induced by diffusive measure-valued GEM processes. These extend the family of diffusive Dirichlet mixtures to the multiparameter case, including dependent Pitman-Yor mixtures as special cases, and have applications to Bayesian nonparametric inference for dynamic density estimation with discretely collected data.

Authors who are presenting talks have a * after their name.
