Attribute Reduction Method Based on Absorption Law of Discernibility Matrix

采用基于可辨识矩阵的约简方法,将属性的约简转化成矩阵的构造化简问题。提出利用吸收律来简化可辨识矩阵的构造过程,通过对属性重要性的度量,构造了一种基于可辨识矩阵吸收律的属性约简算法。通过实例分析并验证了该方法的有效性。

The reduction method based on discernibility matrix is adopted to transform the problem of attribute re- duction into the construction and simplification of matrix. The absorption law is proposed to simplify the process of constructing the discernibility matrix, thus a reduction algorithm on the basis of discernibility matrix absorption is constructed by the measurement of attribute importance. The analysis of examples verified the validity of the method.
