面向不完备信息系统的双论域决策粗糙集——基于双相对量化信息的角度
Decision-Theoretic Rough Sets on Two Universes Within Incomplete Information System:From the View of Double Relative Quantitative Information
摘要
Abstract
Rough set models on two universes are valuable generalizations of classical rough set model. In recent years,different kinds of rough set models on two universes have been established.In order to characterize relative quantitative information within incomplete information system, this paper establishes two kinds of double relative quantitative decision-theoretic rough sets on two universes based on rough set models on two universes,discusses the properties of the proposed models,and explores some interesting relations between above mentioned two mod-els by adjusting different parameters.Finally,this paper uses a SARS dataset to illustrate the definition and relations of the proposed rough set models.关键词
