基于强化正域的属性约简方法
Attribute reduction method based on enhanced positive region
摘要
Abstract
Through a variety of reduction methods were compared,this paper proposed a more precise definition of the positive region based on the traditional attribute dependence in order to get better results.By dividing the boundary region accurately, the dependence of conditional attributes on decision attributes were enhanced,and obtained the results by using the top-down heuristic search algorithm.It used UCI standard data sets to test reduction method based on enhanced positive region REPR. And REPR can reduce the size of the decision tree and improve the classification accuracy,which shows that it can be more ef-ficient for attribute reduction on decision tables than the other classical methods.关键词
