【摘要】 函数S-粗集是用R-函数等价类[u]定义的,函数S-粗集具有规律特征,函数是一个规律,利用函数S-粗集,给出规律挖掘的研究,给出规律挖掘方法与应用,函数S-粗集是寻找系统中未知规律的一个新理论.所给出的研究,在风险投资分析、系统状态识别等多个应用领域中得到应用.函数S-粗集是粗集理论中的一个新的研究方向.更多还原

【Abstract】 Function s-rough sets(function singular rough sets) is defined by R-function equivalence class [u],Function s-rough sets has law characteristic,and a function is a law.Using function s-rough sets,this paper presents the research of law mining,it also presents the approach and application of law mining.Function S-rough sets is a new theory to discover the unknown law in systems.The result of this paper’s research can be applied in many application fields,for example,investment risk analysis,recognition of system status and so on.Function S-rough sets is a new research direction of the rough sets theory.更多还原
