研究集对系统的特性与粗集理论中等价关系之间的联系与转化方式,构建了粗糙联系度函数,探讨了粗糙联系度函数的基本性质与动态特征,形成了面向不完备信息处理领域的粗糙集对分析方法。将粗糙集对分析方法应用到不含有决策属性的信息系统中,分析不同属性集合的分类结果,构建基于概念划分的分类贴近度,进而给出一种新的属性约简方法,最终通过一个实例验证了该方法的合理性与可行性。
The relationship between system characteristics and the equivalence relation in rough set theory is studied. The rough relation function is constructed. The basic properties and dynamic characteristics of rough contact degree function are discussed. Rough set pair analysis method. Applying the method of rough set analysis to the information system without decision attributes, analyzing the classification results of different attribute sets and constructing the closeness of classification based on concept partition, and then giving a new method of attribute reduction, and finally using an example The method is proved to be reasonable and feasible.
