Gaussian Mixture Model
Introduction
Using Expectation Maximization algorithm to implement Gaussian Mixture Model on Old Faithful Dataset. EM algorithm is an iterative optimization technique which is operated locally.Given a Gaussian mixture model, the goal is to maximize
the likelihood function with respect to the parameters
comprising the means and covariances of the components
and the mixing coefficients
