We show that a classifier based on Gaussian mixture models (GMM) can be trained discriminatively to improve accuracy. We describe a training procedure based on the extended Baum-Welch algorithm used in speech recognition. We also compare the accuracy and degree of sparsity of the new discriminative GMM classifier with those of generative GMM classifiers, and of kernel classifiers, such as suppo...

The XCS Library (XCSLib) is an open source C++ library for genetics-based machine learning and learning classifier systems. It provides (i) several reusable components that can be employed to design new learning paradigms inspired to the learning classifier system principles; and (ii) the implementation of two well-known and widely used models of learning classifier systems.
