摘要
S-粗集(singular rough sets)存在三种形式:单向S-粗集(one direction singular rough sets),单向S-粗集对偶(dualof one direction singular rough sets)和双向S-粗集(two direction singular rough sets)。S-粗集具有动态特性,遗传特性,记忆特性和隐藏特性。利用S-粗集,给出了f-隐藏知识,F-隐藏知识,隐藏度和隐藏-依赖度的概念,提出了关于隐藏知识的隐藏定理和隐藏-依赖定理,并给出应用。
S-rough sets (singular rough sets) have three forms: one direction S-rough sets (one direction singular rough sets), the dual of one direction S-rongh sets ( dual of one direction singular rough sets), and two direction S-rough sets( two direction singular rough sets). S-rough sets have dynamic characteristics, genetic characteristics, memorial characteristics and hiding characteristics. By using S-rough sets, the concepts of f-hiding knowledge, F-hiding knowledge, hiding degree and dependence degree were presented, hiding theorem and dependence theorem of hiding knowledge were proposed, and the applications of hiding knowledge were given.
