public class GaussianOutlierEliminator
Single Gaussian based outlier elimination. Looks at the difference distributions of aligned source-target LSF, f0, energy, and
duration features. Eliminates outliers that fall outside user specified ranges. The ranges can be specified using
GaussianOutlierEliminatorParams in the form of total standard deviations for each feature. It is also possible to eliminate too
similar feature pairs to enforce a certain amount of dissimilarity in the training data.
