Scikit-Fuzzy: A New SciPy Toolkit for Fuzzy Logic; SciPy 2013 Presentation


Authors: Warner, Joshua, Mayo Clinic Department of Biomedical Engineering; Ottesen, Hal H., Adjunct Professor

Track: General

Scikit-fuzzy is a robust set of foundational tools for problems involving fuzzy logic and fuzzy systems. This area has been a challenge for the scientific Python community, largely because the common first exposure to this topic is through the MATLAB® Fuzzy Logic Toolbox™. This talk officially introduces a general set of original fuzzy logic algorithms to the scientific Python community which predate the commercial toolbox, were released under the 3-clause BSD license, and were translated to Python by an author who never used the MathWorks® Fuzzy Logic Toolbox™.

The current capabilities of scikit-fuzzy include: fuzzy membership function generation; fuzzy set operations; lambda-cuts; fuzzy mathematics including Zadeh's extension principle, the vertex method, and the DSW method; fuzzy implication given an IF THEN system of fuzzy rules (via Mamdani [min] or Larsen [product] implication); various defuzzification algorithms; fuzzy c-means clustering; and Fuzzy Inference Ruled by Else-action (FIRE) denoising of 1d or 2d signals.

The goals of scikit-fuzzy are to provide the community with a robust toolkit of independently developed and implemented fuzzy logic algorithms, filling a void in the capabilities of scientific and numerical Python, and to increase the attractiveness of scientific Python as a valid alternative to closed-source options. Scikit-fuzzy is structured similarly to scikit-learn and scikit-image, current source code is available on GitHub, and pull requests are welcome.
