摘要
数值信息系统在实际生活中有很广的应用。基于邻域粒化的思想,提出了数值信息系统上的分布约简,分配约简和规则约简,同时给出了邻域关系上的近似分类精度等概念。最后通过区间化的形式描述了决策规则的获取方法,这是对Paw lak知识发现的推广。
Numerical information system in actual life has a wide application.Based on the neighborhood graining thoughts,puts forward the distribution reduction,assignning reduction and rules reduction on the numerical information system,and the neighborhood relationship concepts such as approximate classification accuracy.Finally Through the form of interval described the acquisition method about decision rules,this is the promotion about Pawlak knowledge discovery.
