gmmactiv

Purpose

Computes the activations of a Gaussian mixture model.

Synopsis 


a = gmmactiv(mix, x)

Description

This function computes the activations a (i.e. the probability p(x|j) of the data conditioned on each component density) for a Gaussian mixture model. The data structure mix defines the mixture model, while the matrix x contains the data vectors. Each row of x represents a single vector.
