查询词典 efficiency

The traditional distinction based on the matrix attribute reduction algorithm analysis, for distinction in the matrix "repeat" Too many elements, these "duplicate" elements not only in solving attribute reduction in the process does not work, But also reduce the time efficiency by improving the shortcomings that distinction in the matrix structure in the process of using Proposition calculus in the absorption of the law removed the distinction between the functions of the non-functional "repeat"element, a property Reduction of improved algorithm RADM, improve the efficiency of the attribute reduction.

通过对传统的基于区分矩阵的属性约简算法进行分析后，针对区分矩阵中"重复"元素过多，同时这些"重复"元素非但在求解属性约简的过程中不起作用，而且还降低时间效率这一缺点进行了改进，即在构造区分矩阵的过程中，利用命题演算中的吸收律去掉了在区分函数中不起作用的"重复"元素，提出了一种属性约简的改进算法RADM，提高了属性约简效率。
