Generating Weights for Fuzzy Decision Making Mechanism to Diagnose Heart Disease

Abstract

Heart disease is one of the diseases spread around the world. It suddenly kills the human

community. So use of fuzzy logic to diagnosis the heart disease is essential. So the study was

conducted with the following components. They are fuzzification, fuzzy decision making

mechanism and defuzzification. The crisp values are changed into fuzzy values by

fuzzification. Fuzzy decision making mechanism is based on adaptive neuro fuzzy inference

system which has five layers. In layer 1 the rules are generated with the weights. The weights

for each rule are derived by using S weights. The output parameters are also predicted by

fuzzy predicted value. The fuzzy values from fuzzy decision making mechanism are transferred

into crisp values by defuzzification. With the crisp values the doctors and patients can

diagnose the heart disease. The proposed algorithm was tested with Cleveland heart disease

dataset. The proposed algorithm was implemented using MATLAB fuzzy logic tool box and it

works more effectively than the earlier methods.

Keywords: Fuzzy decision making mechanism, rules, S weight, fuzzy predicted value, heart
