| 摘 要： | 根据Guan等提出的完备信息系统下矩阵约简算法，提出一种改进的属性约简计算方法。该方法根据矩阵的运算特点，通过引入唯一零值概念，使得计算过程更为简易。证明了它与区分矩阵下属性约简的等价性,最后将该方法运用到协调决策表中，并用实例对此进行了说明。

| Abstract: | Based on matrix reduction algorithm for information system introduced by Guan, a new improved computational method of attribute reduction was presented. According to the characteristics of operation between matrixes, the computation was simplified by introducing only the concept of zero value. This method was proved to be equal to attribute reduction by discernable matrix. At last, the method was applied to complete decision table. Its correctness and effectiveness are shown in an example. |
