摘要
首先介绍了粗糙集、模糊集与三角模的概念,接着指出利用三角模可以诱导出相应的包含度,进而可得到一个相似度,提出了一种利用三角模对粗糙集间的相似性进行度量的新方法.最后借助算例验证了该方法的可行性.
The concepts of rough sets,fuzzy sets and triangular norms are discussed firstly.It is showed that an inclusion degree can be induced by a triangular norm,and then the corresponding similarity degree can be obtained consequently.A novel similarity measure between rough sets by means of triangular norm is presented.Finally,the feasibility of proposed method is proved by a concrete example.
