扩展的三支决策理论OA北大核心CSTPCD
Extension of Three-way Decision Theory
三支决策理论只能将决策对象划分到接受域、拒绝域和边界域3类,不能处理把决策对象划分为更多类的情况,因此,立足于传统的三支决策理论,对其进行推广,提出扩展的三支决策理论,结合贝叶斯理论,以决策的平均损失最小为原则,给出扩展的三支决策理论详细推导过程,使经典的三支决策理论成为特例.
In the traditional three-way decision theory,the objects can only be divided into 3 regions:acceptance,rejection or deferment.Therefore the theory can not be applied when the objects must be divided into more than 3 regions.In this paper,an extended theory is proposed,in which,combining the Bayes theory,taking the average minimum loss criterion as principle,the detailed derivation of the extended theory is presented so that the classic three-way dicision the…查看全部>>
