`scikit-learn`-Compatible API Reference
=======================================

This is the class and function reference for the `scikit-learn`-compatible
version of the AIF360 API. It is functionally equivalent to the normal API but
it uses scikit-learn paradigms (where possible) and :class:`pandas.DataFrame` for
datasets. Not all functionality from AIF360 is supported yet. See
`Getting Started <https://github.com/Trusted-AI/AIF360/examples/sklearn/demo_new_features.ipynb>`_
for a demo of the capabilities.

Note: This is under active development. Visit our
`GitHub page <https://github.com/Trusted-AI/AIF360>`_ if you'd like to contribute!
