Introduction to Dirichlet Process Gaussian Mixture Model
Recently I revisited Bayesian nonparametric methods for unsupervised learning. Bayesian statistics is quite a interesting topic that I have worked on a couple years back. Here is a complete derivation to the variational EM algorithm for Dirichlet process mixture model (infinite mixture model) with Gaussian distribution: (link).
