摘要
粗糙集的扩充模型主要有容差关系和相似关系两种,以及这两种模型的改进形式。在此基础上,提出了改进型的限制容差类关系模型,使得其分类更加合理,对这种关系模型的两种特殊情况进行了分析和证明,并提出了基于这种模型的一致性检验和冗余属性删除的方法。
There are several extensions such as tolerance relation, non-symmetric similarity relation and the improved model on them. In this paper, an improved model on limited tolerance relation is developed, with which we can classify the records reasonably, and two special instances are analyzed and testified. Finally, the methods of consistency examination and deleting redundant attributes are proposed.
