Prior selection for the precision parameter of Dirichlet Process Mixtures
Carlo Vicentini, Ian Hyla Jermyn
Consider a Dirichlet process mixture model (DPM) with random precision parameter , inducing clusters over observations through its latent random partition. Our goal i…

The transcoding sampler for stick-breaking inferences on Dirichlet process mixtures
Carlo Vicentini
Dirichlet process mixture models suffer from slow mixing of the MCMC posterior chain produced by stick-breaking Gibbs samplers, as opposed to collapsed Gibbs samplers based on the…
