Supervised Gaussian Mixture Model

Supervised Gaussian Mixture Model. See gaussian mixture models for more information on the estimator. The initial values you mentioned is likely the initial values for the mean vectors and covariance matrices for the gaussians which will be updated by the em algorithm.

Lda is a supervised learning technique where the class priors are known and the class means and covariances can be estimated using training data. After the model is fitted, it is possible to sample new images (in the compressed space) from the gaussian mixture model, each component representing a different concept of those images ( numbers!
