单向S_p-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S_p-上阶梯知识,S_p-上阶梯知识的依信度生成,S_p-上阶梯知识属性依赖的原理,给出S_p-上阶梯知识的属性依赖挖掘定理,S_p-上阶梯知识的状态识别算法.
單嚮S_p-粗集中,具有屬性集α的知識[x](R-元素等價類[x])具有這樣的特徵:若α內被補充屬性,則[x]內的元素箇數被減少.利用這一特徵,攷慮屬性補充的隨機性,給齣S_p-上階梯知識,S_p-上階梯知識的依信度生成,S_p-上階梯知識屬性依賴的原理,給齣S_p-上階梯知識的屬性依賴挖掘定理,S_p-上階梯知識的狀態識彆算法.

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.
