对量化容差关系中由于容差度阈值的变化而引起的论域覆盖的粒度、粗糙集的近似精度与粗糙熵、知识的粗糙熵的度量变化进行了讨论。建立了量化容差关系下知识依赖的概念,并探讨了容差度阈值和知识的变化对知识依赖度量的影响。对量化容差关系所产生的覆盖进行修正,以使得新覆盖的任一模块里的任意元素均两两满足量化容差关系,并进行了相关性质的证明。
The granularity of domain coverage, the approximate accuracy and rough entropy of rough set, and the rough measure of knowledge entropy caused by the change of tolerance threshold are discussed in the quantitative tolerance relationship. The concept of knowledge dependence under quantitative tolerance was established, and the influence of the threshold of tolerance degree and the change of knowledge on the knowledge dependence measure was discussed. The correction of the coverage generated by the quantitative tolerance relationship is made so that any element in any newly covered module satisfies the quantitative tolerance relationship and proves the relevant properties.
