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.
