Project Summery

This project is an implementation of a heart disease diagnosis system using a fuzzy expert system. Finally, the output determines whether or not a person has heart disease. There are three main steps inorder to do so: 1- Fuzzification 2-Inference 3-Defuzzification

To solve the problem with the help of fuzzy logic, we convert our values from absolute to fuzzy (imprecise, relative). This stage is called Fuzzification. For this purpose, fuzzy sets should be defined and according to the membership function, the membership of each value to the set should be calculated.

In the next step, it is necessary to check the obtained fuzzy values in the existing rules to solve the problem. This stage is called Inference.

The last step is called Defuzzification. At this stage, we return to the world of absolute values with the help of repeated deductions to obtain the answer in the form of absolute values.
