LensKit 0.5.0 modifies the algorithm APIs to follow the SciKit design patterns instead of our previous custom patterns. Highlights of this change:
- Algorithms are trained in-place — we no longer have distinct model objects.
- Model data is stored as attributes on the algorithm object that end in
- Instead of writing
model = algo.train_model(ratings), call
We also have some new capabilities:
- Ben Frederickson’s Implicit library
A number of improvements, including replacing Cython/OpenMP with Numba and adding ALS.
A lot of fixes to get ready for RecSys.
