摘要/Abstract

摘要： 利用变异知识的概念，提出了变异知识过滤度的概念，对变异知识［α/R］的颗粒特征、过滤特征进行了讨论.以此为基础，进一步提出了变异知识族的粒度、过滤度的概念，分析了变异知识族颗粒特征、过滤特征.利用这些结果，给出变异知识过滤-分离原理和变异知识过滤剩余-分离原理.

关键词: 变异粗集, 变异知识, 变异知识族, 变异知识粒度, 变异知识过滤度

Abstract: By using concept of variation rough sets, this paper presents the concept of filter degree of variation knowledge, the characters about granulation and filter of variation knowledge ［α/R］ are also discussed. We further present the concepts of the granulation degree and filter degree of variation knowledge sets, and analyze the characters about granulation and filter of variation knowledge sets. Using these results, this paper presents filter-separation principle and filter surplus-separation principle of variation knowledge.

Key words: variation knowledge, variation knowledge sets, granulation degree of variation knowledge, filter degree of variation knowledge , variation rough sets
