Research on Data Mining for Attribute Reduction Based on Rough Set Theory

Shen Chen-ming

Abstract

Rough set theory is a mathematical tool to study the processing of incomplete and uncertain knowledge,of which attribute reduction is one of the essential parts.This paper expounds the basic ideas of rough set theory and introduces illuminating algorithm for minimum reduction.Finally an example is given to testify the practicability and efficiency of the algorithm.
