Fuzzy Inference System Based on Rough Sets and Its Application to Medical Diagnosis

  • Chapter

Part of the book series: Theory and Decision Library ((TDLD,volume 11))

Abstract

In this paper, a method of constructing fuzzy if-then rules in an expert system is described by the proposed approach, where the lower approximations in rough sets are used to extract if-then rules from the given information system and fuzzy if-then rules are constructed from the extracted if-then rules.
