scikit-fuzzy is a fuzzy logic toolkit for SciPy.

The goals of scikit-fuzzy are:

  • To provide the community with a robust toolkit of independently developed and implemented fuzzy logic algorithms
  • To increase the attractiveness of scientific Python as a valid alternative to closed-source options.

Please cite DOI if you find scikit-fuzzy useful. A formal paper describing this package is in preparation.




The documentation of the library can be found here : http://pythonhosted.org/scikit-fuzzy

Scikit-Fuzzy depends on

  • NumPy >= 1.6
  • SciPy >= 0.9
  • NetworkX >= 1.9

and is available on PyPi! The lastest stable release can always be obtained and installed simply by running

$ pip install -U scikit-fuzzy

which will also work to upgrade existing installations to the latest release.

If you prefer to install from source or develop this package, you can fork and clone this repository then install SciKit-Fuzzy by running

$ python setup.py install

or develop locally by running

$ python setup.py develop

If you prefer, you can use SciKit-Fuzzy without installing by simply exporting this path to your PYTHONPATH variable.

IEEE Rounding for Matlab users

It should be noted that Matlab rounds incorrectly. The IEEE standard (which is how this package behaves) requires rounding to the nearest EVEN number if exactly between, e.g. 1.5 --> 2; 2.5 --> 2; 3.5 --> 4; 4.5 --> 4, etc. This minimizes systematic rounding error. Thus, if re-implementing algorithms from Matlab code, slight inconsistencies in rounded results are expected. These are not bugs, and will not be fixed.
