fuzzBuzz: FUZZY INFERENCE SYSTEM FROM SCRATCH

Library Usage Example

Control Fan Speed based on temperature and humidity

1. Without visualization plots

   python usage.py
   

2. With visualization plots

   • Install numpy and matplotlib

     pip install numpy matplotlib
     

   • Usage:

     python usage_viz.py
     

Plots

1. Membership functions of input and output variables along with fuzzification of input variables

2. Detailed Rule Activation

3. Combined Rule Activation

4. Defuzzification

Application: Edge Detection
