- Abstract:
-
The rough Vague set is a theoretical tool that combines the theories of rough and Vague sets to deal with uncertain information. In this paper, we introduce the concept of relative entropy and its coefficient to a rough Vague set to investigate a method for measuring relative entropy, its coefficient, and the similarity of Vague and rough fuzzy sets. We also analyzed their main properties. We verified that the coefficient of the relative entropy has similarity with that of rough Vague sets, and that this coefficient can be used to measure the similarity of rough Vague sets. Finally, we conducted a case study to verify the effectiveness of using the relative entropy coefficient of a rough Vague set to determine the degree of similarity between rough Vague sets. This theory provides a new method for measuring the similarity of rough Vague sets.
