Infinite Mixture of Inverted Dirichlet Distributions

no code implementations27 Jul 2018 Zhanyu Ma, Yuping Lai

In this work, we develop a novel Bayesian estimation method for the Dirichlet process (DP) mixture of the inverted Dirichlet distributions, which has been shown to be very flexible for modeling vectors with positive elements.
