不完备区间值模糊信息系统的粗糙集理论
Rough set theory for incomplete interval-valued fuzzy information systems
摘要
Abstract
By considering the incompleteness and uncertainty of information systems,the rough set theory for the incomplete interval-valued fuzzy information systems is discussed, and several properties of the rough approximation operators are showed.In addition,the knowledge discovery for the incomplete interval-valued fuzzy information systems is studied.As an application,the decision rule and the attribute reduction are presented based on an incomplete interval-valued decision table.关键词
