摘    要:单向Sp-粗集中,具有属性集α的知识x](R-元素等价类x])具有这样的特征:若α内被补充属性,则x]内的元素个数被减少。利用这一特征,考虑属性补充的随机性,给出Sp-上阶梯知识,Sp-上阶梯知识的依信度生成,Sp-上阶梯知识属性依赖的原理,给出Sp-上阶梯知识的属性依赖挖掘定理,Sp-上阶梯知识的状态识别算法。

关 键 词:Sp-上阶梯知识  属性依赖  依信度生成  依赖挖掘  单位圆定理  状态识别  挖掘算法

Abstract:In one direction S_p-rough Sets,the knowledge x](R-element equivalence class x])with the attribute set ot has such characteristic:If there are new attributes supplemented to α,then the elements in x]will decrease;By using these characteristics and considering the reliability characteristics of the element transference random,the concepm of S_p-upper ladder knowledge,the generation of depending on reliability of S_p-upper ladder knowledge,and attribute dependence of S_p-upper ladder knowledge are presented-Attribute dependence mining theorem of S_p-upper ladder knowledge,and attribute dependence algorithm are also given.
Keywords:Sp-upper ladder knowledge  attribute dependence  generation of depending on reliability  dependence mining  unit circle theorem  state recognition  mining algorithm
