基于变精度粗糙集的不完备决策表属性约简
Attribute reduction based on variable precision rough set in incomplete decision table
摘要
Abstract
In view of the limitations of the attribute reduction algorithm based on variable precision rough set in tolerance rela-tion, the judgment theorems and discernibility matrixes with respect to β upper(lower)distribution reductions are presented.The method for β upper(lower)distribution reduction in incomplete decision table is also presented. At last, the experiment demonstrates the effectiveness of the proposed method.关键词
