摘要
针对区分矩阵属性约简算法中区分矩阵存在空值元素和重复元素等缺点,提出了一种基于二进制差别矩阵的属性约简算法.该算法不仅保证了属性约简的完整性和正确性,同时也降低了运算所需的时间和空间.
Aimming at the shortages of discernibility matrix that contains null elements and duplicate elements,a method of attributes reduction based on binary discernibility matrix was presented in this paper.It not only guarantees the integrity and accuracy of the attributes reduction results,but also cuts down the time and space of the operation.
