不协调覆盖决策系统下属性约简的新的注记
Notes on attribute reduction based on inconsistent covering decision system
摘要
Abstract
This paper discusses some notes on attribute reduction based on inconsistent covering decision system.It proposes the correlative definitions of inconsistent covering decision and conditional limitary entropy.It introduces the properties and theorems under the positive region and the conditional information entropy.It uses a discernibility matrix to design an algorithm that computes all the reducts of inconsistent covering decision system.The experiment results show the effectiveness.关键词
