mdn2gmm

Purpose

Converts an MDN mixture data structure to array of GMMs.

Synopsis 

gmmmixes = mdn2gmm(mdnmixes)

Description

gmmmixes = mdn2gmm(mdnmixes) takes an MDN mixture data structure mdnmixes containing three matrices (for priors, centres and variances) where each row represents the corresponding parameter values for a different mixture model and creates an array of GMMs. These can then be used with the standard Netlab Gaussian mixture model functions.

Example 


mdnmixes = mdnfwd(net, x);
mixes = mdn2gmm(mdnmixes);
p = gmmprob(mixes(1), y);
This creates an array GMM mixture models (one for each data point in x). The vector p is then filled with the conditional probabilities of the values y given x(1,:).
