The mixture of Gaussians generative model
		• First pick one of the k Gaussians with a probability that is called its “mixing proportion”. • Then generate a random point from the chosen Gaussian. • The probability of generating the exact data we observed is zero, but we can still try to maximize the probability density. – Adjust the means of the Gaussians – Adjust the variances of the Gaussians on each dimension (or use a full covariance Gaussian). – Adjust the mixing proportions of the Gaussians.
