【摘要】 讨论了可辩识矩阵的内容的深层次含义,分析了它与属性值约简的关系,并提出了一种利用可辩识矩阵实现属性值约简的方法,分析了利用可辩识矩阵实现属性约简和属性值约简的方法,设计了基于可辩识矩阵的最佳约简的算法,使得属性约简和属性值约简得以一致计算,使知识推理过程变得统一且相对简单.更多还原

【Abstract】 A new reducting method is proposed for data mining, the imblication of discernibility matrixes is dijcassed and the relationships between attribute reducts and value reducts are analyzed. The proposed optimal reducing algorithm based on discernibility matrixes, makes the attribute reducing well accord with attribute value reducing and simpler to apply.更多还原
