HeartDiseaseDiagnosis-FuzzySys

The aim of this project is to diagnose heart disease based on a fuzzy expert system.

Inputs

1. Blood Pressure
2. Blood Sugar
3. Cholesterol
4. Heart Rate
5. ECG
6. Old Peak
7. Age

• The fuzzy sets of these values are available Here.

Crisp Inputs

1. Chest Pain 1: Typical Angina, 2: Atypical Angina, 3: Non-Anginal Pain, 4: Asymptomatic

2. Sex 0: Male, 1: Female

3. Exercise 0: This person is not allowed to have sport activities. 1: This person is allowed to have sport activities

4. Thallium 3: Normal 6: Medium 7: High

Steps

This project includes four steps:

1. Fuzzification: Based on Inputs and Fuzzy Sets
2. Inference: Based on the Rules
3. Defuzzification: Based on Diagram of Output Values and This Formula of the Center of the Mass (CoG):

$$x^*=(\sum_{i=1}^{n} μ_C^― (x_i).x_i)/(\sum_{i=1}^{n} μ_C^― (x_i))$$

4. Final Result
