Attribute reduction based on partition in information system
基于划分的信息系统属性约简

Based on the viewpoint that attributes have different partition ability, left-partition and right-partition of the attributes were proposed. Characteristics and properties of them were investigated. The judgment method of core attribute was given in regard to the attribute partition view. A new attribute reduction algorithm named ARABP based on attribute partition was brought forward, and the validity of the algorithm was illustrated by theoretical analysis and experimental results.
