The Modified Algorithm of Attribute Reduction Based on Rough Set Theory

Song Zhi-cha

Abstract

This paper researches attributes reduction of Rough Set Theory. Put forward a modified algorithm of heuristic attribute reduction,this algorithm based on attribute weighted frequency,consider the impact of attribute at the same time. The experimental results show that the algorithm is verified to be more feasible and effective.
