摘要
利用变异S-粗集理论和属性迁移的随机性,给出双向变异S-粗集的依概率生成;讨论了双向变异S-粗集的概率特性.
Based on two-direction variation S-rough sets and randomness of attribute＇s transfer, probability generation of two-direction variation S-rough sets was put forward. The probability characters of two-direction variation S-rough sets were discussed.
