| 摘 要： | 粗糙集方法是一种有效的处理分类问题的方法,但是它在面对高维数据时,很难依靠属性约简提取出泛化能力较高的规则.这是由于粗糙集约简本身在一定程度上忽略了对象个体对信息系统的影响.为避免此问题,通过描述各个对象与其补集间的差别,提取了各个对象所包含的分类信息.在此基础上,设计了一种新的基于粗糙集的规则提取算法.通过实验分析,...

| Abstract: | Rough set method is an effective method of classification,but with high-dimensional data,it is difficult to rely on reduction to extract the rules which have high generalization capability,because the reduction of rough set itself fails to notice the effect of the object on the information system to a certain degree.This paper describes the differences between different objects and extracts the classified information of every object.Then a new rules extraction method is designed based on rough set.And the a... |
