Machine Learning with Dirichlet and Beta Process Priors: Theory and Applications

Paisley, John William - 2010

Dirichlet process and the beta process are the two respective Bayesian nonparametric priors selected for handling these issues … modalities within a data set. For the beta process, we present a new stick-breaking construction for the infinite …

A class of neutral to the right priors induced by superposition of beta processes

Blasi, Pierpaolo De; Favaro, Stefano; Muliere, Pietro - Collegio Carlo Alberto, Università degli Studi di Torino - 2009

A random distribution function on the positive real line which belongs to the class of neutral to the right priors is defined. It corresponds to the superposition of independent beta processes at the cumulative hazard level. The definition is constructive and starts with a discrete time process...
