## Description

Nonparametric Bayesian methods make use of
infinite-dimensional mathematical structures to allow the practitioner
to learn more from their data as the size of their data set grows.
What does that mean, and how does it work in practice? In this
tutorial, we'll cover why machine learning and statistics need more
than just parametric Bayesian inference. We'll introduce and study
a foundational nonparametric Bayesian model known as the Dirichlet process.
Along the way, we'll see what
exactly nonparametric Bayesian methods are and what they accomplish.
