This tutorial covers the Dirichlet distribution, Dirichlet process, Polya urn (and the associated Chinese restaurant process), hierarchical Dirichlet Process, and the Indian
14 Oct 2008 's represent the patrons of the restaurant. From the above conditional probability distribution, we can see that a customer is more likely to sit at a table if there are already many people sitting there. However, with probability proportional to ?, the customer will sit at a new table. Also known as the ?clustering

27 Jul 2017 Dirichlet Distribution. The Dirichlet distribution is a multivariate distribution whose components all take values on (0,1) and which sum to one. The Dirichlet distribution is frequently used to describe uncertainty about the probabilities of a Multinomial distribution. As such, the Dirichlet distribution is to the
exam paper and is presented here as a tutorial. No motivation is given (in what I've excerpted here), and this document is intended to be a mathematical tutorial that is still accessible to the engineer. I. THE DIRICHLET DISTRIBUTION. Consider the finite, D-dimensional vector, ?, having the properties 0 ? ?i ? 1, i = 1,,D
Abstract. This tutorial covers the Dirichlet distribution, Dirichlet process, Polya urn (and the associated Chinese restaurant process), hierarchical Dirichlet Process, and the Indian buffet process. Apart from basic properties, we describe and contrast three methods of generating samples: stick-breaking, the Polya urn,.
