Two direction variation S-probability rough sets and its attribute probability characters
【摘要】 利用双向变异S-粗集的属性动态迁移特性,结合知识库中的统计信息,提出了双向变异S-概率粗集.讨论了双向变异S-概率粗集的属性概率性质,为获得动态的决策规则奠定了基础.利用上述讨论,给出了一个具体的应用实例.
【Abstract】 Based on attribute’s dynamic transfer property of two direction variation S-rough sets and statistical information in knowledge base,the two direction variation S-probability rough sets was put forward.The attribute’s probability characters of two direction variation S-probability rough sets were discussed.These properties are the bases of dynamic decision-making.Using the above discussion,a special application example was given.
