Thai characters recognition based on tolerant rough sets with fuzzy c-mean

Abstract

This paper presents a method of using fuzzy c-mean in combination withrough sets for recognizing Thai Characters. The clusters made by fuzzy c-meanalgorithm alone may compose of many types of data, which is the problem forrecognition system. By coupling fuzzy c-mean with rough sets, the status oflower and upper approximation will be associated to all created clusters. We cansplit the clusters which have upper approximation status until they becomelower approximation set. With most clusters as lower approximation set, we canclearly state the type of members of each cluster and that will help improve theaccuracy of the Thai characters recognition system.
