1. Secondly, we investigate the method of discernibility matrix and function. 其次,我们对差别矩阵差别函数的方法进行了研究。
2. It corresponds approximately to Freud's superego and is the ground for discernibility and difference. 它大约相当于弗洛伊德“超我”的概念,而且是区分和分化的前提。
3. Discernibility ability index DI(a) of decision table is defined, some properties about DI(a) are presented. 根据决策表定义条件属性区分能力指数DI(a)的概念,给出DI(a)的若干性质。
4. The definitions of SRS and two theorems of computing the feature weights based on discernibility matrix are presented. 给出了相似粗糙集 的基本定义,以及利用该方法 基于 差别矩阵进行特征权值计算 的两个定理。
5. Discernibility matrix and discernibility function are a powerful tool seeking nuclear attributes and attribute reduction. 区分矩阵和区分函数是求核和约简的有力工具。
