Abstract

In rough set theory,data reduction is a very important issue,it includes attributes and attribute values reduction.Others are looking for a proven information system of the best reduction is a NP-problem.This paper mainly based on the study of a binary tree data reduction method,experimental results show that the algorithm in most cases be able to effectively obtain information system of an optimal reduction.
