摘要
概述了两类属性约简算法,并基于可辨矩阵首次提出了差别矩阵的定义,研究了差别矩阵的基本性质,并给出了基于差别矩阵的属性约简算法,通过与其他算法的比较得出该算法是有所改进的。
This paper summarizes two kinds of attributes reduction algorithm, brings up the definition of differentiability matrix on the basis of the discernibility matrix for the first time, and analyses its basic characters. Then gives an algorithm, and this algorithm is confirmed to have improvements by compared with the other algo- rithms.
