Parallel Gibbs Sampling for Hierarchical Dirichlet Processes via Gamma Processes Equivalence
Published on 2014-10-082337 Views
The hierarchical Dirichlet process (HDP) is an intuitive and elegant technique to model data with latent groups. However, it has not been widely used for practical applications due to the high computa
