摘要
利用函数单向S-粗集的结构,给出函数迁移的信度特征、函数集Q的下近似信度特征和函数集Q的上近似信度特征.利用这些结果,给出函数单向S-粗集的信度特征,提出函数单向S-粗集的随机结构与随机定理,得出函数单向S-粗集的结构是函数单向S-粗集的随机结构的特例,函数单向S-粗集的随机结构是函数单向S-粗集结构的一般形式.
By employing one direction singular rough sets of function, the confidence characteristic of function transfer, the lower approximation of function sets and upper approximation of function sets were proposed. Based on these results above, the confidence characteristic of one direction singular rough sets of function was given, and the random structure and the random theorem of one direction singular rough sets of funetion were presented. The structure of one direction singular rough sets of function is a special case of the random structure of one direction singular rough sets of function, and the random structure of one direction singular rough sets of function is the general form of the structure of one direction singular rough sets of function.
