Study and Improvement of Reduction Algorithm Based on Discernibility Matrix

Dajiang Wang

Abstract

On the basis of a detailed discussion of reduction algorithm based on discernibility matrix, some improvements of the algorithm are made in this paper,and a quick reduction algorithm based on discernibility matrix is proposed; besides, a simplification of discernibility matrix is made when the value of decision attribute has a small variety.
