摘要 在P-集合的基础上给出了数据w的(F^-,F)-挖掘、挖掘尺度和挖掘还原系数的概念,讨论了数据w的属性特征,得到数据w挖掘的可分辨定理、数据的外还原与数据的内还原定理.为数据处理提供了一个新的数学工具. Based on P-sets,the concepts of(F^-,F)-mining,mining measurement and mining recovery coefficient about data are proposed.Moreover,the attribute characteristics of the data are discussed.The data mining discernibility theorems,the outer recovery theorem of the data,and the internal recovery theorem of the data are presented.A new mathematics tool is got.
