Abstract

This paper is concerned with the problem of probability density function estimation using mixture modelling. In [7] and [3], we proposed the Predictive Validation, PV , technique as a reliable tool for the Gaussian mixture model architecture selection. We propose a modified form of the PV method to eliminate underlying problems of the validation test for a large number of test points or very complex models.
