摘要
S-粗集(Singular rough sets)是对Pawlak Z粗集的改进,单向S-粗集(One direction singular rough sets)是S-粗集的基本形式之一.利用单向S-粗集,本文给出数据属性,数据分层挖掘概念,数据分层挖掘序定理,合成数据分层挖掘定理,及数据分层挖掘准则,利用这些结果,给出应用.说明单向S-粗集是动态数据分层挖掘研究的一个新工具.
S-rough set （Singular rough sets） improved Pawlak Z rough set;and one direction S-rough set （one direction singular rough sets） is one of the basic forms of S-rough set. By employing one direction S-rough set, the concepts of data attribute and data hierarchical mining were proposed;then the order theorem of data hierarchical mining, the hierarchical mining theorem of compound data,and the hierarchical mining principle of data were presented; based on the results above,the application was given. One direction S-rough set is a new instrument for the research of dynamic hierarchical mining of data.
