摘要
利用P-集合与它的动态特性,定义了内、外P-对偶信息及P-对偶属性信息。利用这些概念,提出了P-信息依赖度、依赖系数,P-对偶信息依赖度、依赖系数;讨论了内、外P-属性信息依赖定理,P-对偶信息获取-发现定理及内潜藏原理,得出P-对偶信息依赖-获取两个准则。最后给出P-对偶信息的应用。
The concepts of inner and outer P-dual information and P-dual attribute information are defined by using dynamic characteristic of P-sets. On the basis of these concepts, dependence and dependence degree, dependence coefficient of P-information and P-dual attribute information are given. Inner and outer P-attribute information dependence theorems, P-dual information acquirement-discovery theorem and inner hidden theorem are discussed. Two dependence-acquirement criterions are gotten on P-dual information. In the end, the application of P-dual information is presented.
