This tutorial introduces nonparametric Bayes (BNP) as a tool for modern data science and machine learning. BNP methods are useful in a variety of data analyses---including density estimation without parametric assumptions and clustering models that adaptively determine the number of clusters. We will demonstrate that BNP allows the data analyst to learn more from a data set as the size of the data set grows and see how this feat is accomplished. We will describe popular BNP models such as the Dirichlet process and Chinese restaurant process, BNP inference procedures, and recent advances in the field.



Working knowledge of Bayesian data analysis. Know how to use Bayes' Theorem to calculate a posterior for both discrete and continuous parametric distributions. Have a basic knowledge of Markov chain Monte Carlo (especially Gibbs) sampling for posterior approximation.

What we won't cover

Gaussian processes are an important branch of nonparametric Bayesian modeling, but we won't have time to cover them here. We'll be focusing on the discrete, or Poisson point process, side of nonparametric Bayesian inference.
