See Density Estimation for a Gaussian mixture for an example on plotting the density estimation. 2.1.1.1. Pros and cons of class GaussianMixture ¶ 2.1.1.1.1. Pros¶ Speed: It is the fastest algorithm for learning mixture models. Agnostic: Webtrix Σi for the ith Gaussian, µi the mean of the same. We also associate a prior probability ai with the ith Gaus-sian with regard to its contribution to the mixture. – Our goal is automatic clustering of the observations into disjoint clusters, which each cluster corresponding to a single Gaussian. – The question here is whether EM can
