Improvement of the Attribute Reduction Algorithm Based on Rough Set

Liu Ting-cang

Abstract

Attribute reduction is one of the key topics in the rough set theory field,the authors discuss the attribute reduction in rough sets theory.Firstly,the basic attribute reduction algorithm in discernibility matrix is introduced.Then,according to the algorithm of rough sets-GENRED,a new attribute reduction algorithm based on rough sets,is proposed.And the new algorithm can meet the requirement of the attribute reduction and improve the operating efficiency.
