DPGMM.js

DPGMM.js is a JavaScript implementation of a Dirichlet process gaussian mixture model (DPGMM). Live Demo

The Dirichlet process is a stochastic process used in Bayesian nonparameteric models of data, particularly in infinite mixture models. It can be used to build clustering algorithms which do not make a-priori assumptions about the number of components in the data.

Dependencies

The project relies on the following dependencies:

• require.js
• d3
• numeric.js
