Research Abstract

The systematization of discriminative training methods was conducted based on equivalence between misclassification measure and functional margin and on a unified formalization of microscopic- and macroscopic-unit classification. In addition, a geometric margin was derived for a general class of discriminant functions, and a new MCE method was developed by employing the geometric margin as the misclassification measure. The incremental-MCE method was also formalized that consisted of stepwise MCE training for the elemental weak classifiers. The results were implemented in educational software named DISCERN.
