An Information Representation for Attribute Reduction of Decision Tables in Rough Set Theory

Xu Xue

Abstract

In this paper, relationships between attribute reduction of decision tables and information entropy have been mainly discussed. In a consistent decision table, the equivalence properties between algebraic representation and information representation of attribute reduction are proved. Through examples, it shows that attribute reduction of an inconsistent decision table cannot entirely be represented by information entropy.
