Posterior sampling from $\varepsilon$-approximation of normalized completely random measure mixtures

2016 · Electronic Journal of Statistics

This paper adopts a Bayesian nonparametric mixture model where the mixing distribution belongs to the wide class of normalized homogeneous completely random measures. We propose a truncation method for the mixing distribution by discarding the …
The Semi-Hierarchical Dirichlet Process and Its Application to Clustering Homogeneous Distributions

2021 · Bayesian Analysis

Assessing homogeneity of distributions is an old problem that has received considerable attention, especially in the nonparametric Bayesian literature. To this effect, we propose the semi-hierarchical Dirichlet process, a novel hierarchical prior that extends the …
