Design and Implementation of Fuzzy Expert System for Dengue Diagnosis

Abstract

Medical diagnosis expert system is one among the best elements of expert system. This paper utilizes fuzzy expert system to raise the diagnosis level of dengue fever and early detection of dengue in patient. Fuzzy expert system is one of the most traditional artificial intelligence techniques to diagnose any disease. This paper uses MATLAB fuzzy logic toolbox to create an expert system, which is based on crisp values, rules, and defuzzification. The design of fuzzy expert system relies on patient symptoms with diagnosing report as input variable. To analyze the proposed system, accuracy, sensitivity, and specificity are measured.
