基于海明距离函数,给出了Vague集2种新的相似度量方法.根据不确定信息处理的实际背景,利用Vague集的相似度量应该遵循的5项准则,对常见的几种相似度量性质进行了逐一检验,并将这几种相似度量进行比较,指出了它们的不足.
Many measures of similarity between vague sets have been proposed and researched in recent years. Based on the background of fuzzy information handling, some rules have been proposed by author when giving a similarity measure between vague sets and its elements. According to these rules, some existing measures of similarity are reviewed. Moreover, two measures of similarity for vague sets are proposed based on Hanming distence functions.
