LensKit for Python: Next-Generation Software for Recommender System Experiments
arXiv.org
03 Sep 2020
Abstract
LensKit is an open-source toolkit for building, researching, and learning
about recommender systems. First released in 2010 as a Java framework, it has
supported diverse published research, small-scale production deployments, and
education in both MOOC and traditional classroom settings. In this paper, I
present the next generation of the LensKit project, re-envisioning the original
tool's objectives as flexible Python package for supporting recommender systems
research and development. LensKit for Python (LKPY) enables researchers and
students to build robust, flexible, and reproducible experiments that make use
of the large and growing PyData and Scientific Python ecosystem, including
scikit-learn, TensorFlow, and PyTorch. To that end, it provides classical
collaborative filtering implementations, recommender system evaluation metrics,
data preparation routines, and tools for efficiently batch running
recommendation algorithms, all usable in any combination with each other or
with other Python software.
This paper describes the design goals, use cases, and capabilities of LKPY,
contextualized in a reflection on the successes and failures of the original
LensKit for Java software.
