Abstract

As a powerful tool for the representation of classifying knowledge, fuzzy classification rules can not only effectively deal with imprecise and uncertain data, but also possess readability and interpretability. Fuzzy granular rules, also to be a kind of fuzzy classification rules, can be induced by fuzzy information granules. It has been acknowledged that one of the important criteria for evaluating the quality of information granules comes from the principle of justifiable granularity. Unfortunately, the existing methods for extracting fuzzy granular rules fail to take into account the principle of justifiable granularity. In view of the advantages of the justifiable granularity principle in classifying knowledge, we propose in this article a new method of extracting fuzzy granular rules using the justifiable granularity principle and a fusion strategy and establish a fuzzy granular rule-based classifier (FGRBC). Specifically, the justifiability of fuzzy granules is first presented according to both coverage and specificity of fuzzy granules, on which a rule extraction method is formulated to obtain a set of fuzzy granular rules. Furthermore, a fusion strategy is put forward to generate a set of fused rules. Then, the two sets of rules are combined and attribute reduction is performed on the combined rule set. Finally, the reduced combined rule set is employed to construct FGRBC. Moreover, performance of FGRBC is evaluated by numerical experiments and the results show that FGRBC is of satisfactory classification ability.
FGRBC:使用合理粒度原则和融合策略的基于模糊粒度规则的新型分类器
模糊分类规则作为分类知识表示的有力工具,既能有效处理不精确和不确定的数据,又具有可读性和可解释性。模糊颗粒规则也是一种模糊分类规则,它可以由模糊信息颗粒产生。人们已经认识到,评价信息颗粒质量的重要标准之一是合理粒度原则。遗憾的是,现有的模糊颗粒规则提取方法没有考虑合理粒度原则。鉴于合理粒度原则在知识分类中的优势,本文提出了一种利用合理粒度原则和融合策略提取模糊颗粒规则的新方法,并建立了基于模糊颗粒规则的分类器(FGRBC)。首先根据模糊颗粒的覆盖度和特异性提出了模糊颗粒的正当性,并在此基础上提出了一种规则提取方法,得到一组模糊颗粒规则。在此基础上,提出了一种融合策略来生成一组融合规则。然后,将两组规则合并,并对合并后的规则集进行属性约简。最后,利用简化后的组合规则集构造FGRBC。通过数值实验对FGRBC的性能进行了评价,结果表明FGRBC具有良好的分类能力。
