不完备区间值模糊信息系统的粗糙集理论OACSCDCSTPCD
Rough set theory for incomplete interval-valued fuzzy information systems
考虑到模糊信息系统的不完备性和信息值的不确定性,讨论了不完备区间值模糊信息系统的粗糙集理论,给出了粗糙近似算子的性质.研究了不完备区间值模糊信息系统上的知识发现,提出了基于不完备区间值决策表的决策规则和属性约简,最后给出算例.
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-valu…查看全部>>
