A n o v el approach to scoring Gaussian mixture models is presented. Feature vectors are assigned to the individual Gaussians making up the model and log-likelihoods of the separate Gaussians are computed and summed. Furthermore, the log-likelihoods of the individual Gaussians can be decomposed into sample weight, mean, and covariance log-likelihoods.(More)
