基于最大相容类的不完备模糊目标信息系统规则提取

Rule Acquisition in Incomplete and Fuzzy Objective Information Systems Based on Maximal Compatible Classes

本文通过分析不完备信息系统中M.Kryszkiewicz相容关系及最大相容类,提出了基于最大相容类的不完备模糊目标信息系统的粗糙集模型,进一步讨论了利用粗糙隶属函数获得决策规则的方法,并通过实例说明了方法是可行的。

Rough set model based on maximal compatible classes in incomplete and fuzzy objective information are proposed by analyzing M.Kryszkiewicz＇s tolerance relation and maximal compatible classes in incomplete information system, and furthermore approaches to decision rule acquisition are discussed by use of rough membership function. Finally, an example illustrates the approaches are valid.
