October 11th NP Bayes Meetup

In today’s NP Bayes discussion group we returned to the 2006 Hierarchical Dirichlet Process (HDP) paper by Teh et al to discuss sampling-based inference. We spent most of our time sorting through the notational soup needed to specify the HDP variables and their relationships between one another. This led to a brief discussion of implementation issues, and finally a description of the three Gibbs sampling techniques presented in the paper.
