Welcome to Ex-Fuzzy’s documentation!

Ex-Fuzzy is a library to perform fuzzy logic inference using fuzzy logic, with a special focus on the explainable features of approximate reasoning. Different fuzzy sets are supported, and rules are fitted to a dataset using genetic optimization. We also support fuzzy cognitive_maps.

Check out the Getting Started section for a few examples.
