C++ Neural Networks and Fuzzy Logic: Preface

Step Five: Defuzzify the Outputs

In order to control the HeatKnob, we need to obtain a crisp dial setting. So far, we have several of the

IF–THEN rules of the fuzzy rule base firing at once, because the inputs have been fuzzified. How do we

arrive at a single crisp output number ? There are actually several different strategies for this; we will consider

two of the most common, the center of area (COA) or centroid method, and the fuzzy Or method. The easiest

way to understand the process is with an example.
