双精度容差关系决策粗糙集及其属性约简
Decision-theoretic rough set and reduction of dual-variable precision tolerance relation
摘要
Abstract
Based on rough set theory and Bayes theory,it expended the decision-theoretic rough set.In order to research decision-theoretic rough set in incomplete interval-valued information system,first,it came up with the similarity degree and proposed the dual-variable precision tolerance relation.Then,based on the relation,it established the decision-theoretic rough set model in the incomplete interval-valued information system.Then it redefined the definition of uncertainty measure and studied the reduction of the model.Finally,it proposed the reduction algorithm and applied to a target recognition example.关键词
