Algorithm Summary
=================

.. py:module:: lenskit.algorithms

LKPY provides general algorithmic concepts, along with implementations of several
algorithms.  These algorithm interfaces are based on the SciKit design patterns
:cite:p:`Buitinck2013-ks`, adapted for Pandas-based data structures.


All algorithms implement the `standard interfaces`_.
