摘要
信息系统的属性约简是知识发现的核心,将直觉模糊随机变量引入信息系统,定义了直觉模糊随机信息系统.将随机概念推广到直觉模糊模型上,针对直觉模糊随机信息系统的属性约简,给出了直觉模糊随机信息系统下的期望相关关系.基于此关系,讨论直觉模糊随机信息系统属性约简的判定和方法,并通过实际例子分析该法的有效性.
Attribute reduction of information system is the core of knowledge discovery, the article introduced the intuitionistic Fuzzy Random variable into information system, defined the intuitionistic fuzzy random information systems. The random is extended to intuitionistic fuzzy model, in view of the intuitionistic Fuzzy Random attributes reduction of information system, gives the expectations of the relationship under the intuitionistic Fuzzy Random information system, based on this relation, discussed the intuitionistic fuzzy random decision and methods of the attribute reduction of information system, and through the actual examples analysis of the effectiveness of this method.
