public static class LossMixtureDensity.MixtureDensityComponents
This class is a data holder for the mixture density
components for convenient manipulation.
These are organized as rank-3 matrices with shape
[nSamples, nLabelsPerSample, nMixturesPerLabel]
and refer to the 'alpha' (weight of that gaussian), 'mu' (mean for that
gaussian), and 'sigma' (standard-deviation for that gaussian).
