These utility functions are useful for data processing.
Miscellaneous utility functions.
Clone an algorithm, but not its fitted data. This is like
scikit.base.clone(), but may not work on arbitrary SciKit estimators. LensKit algorithms are compatible with SciKit clone, however, so feel free to use that if you need more general capabilities.
This function is somewhat derived from the SciKit one.
>>> from lenskit.algorithms.basic import Bias >>> orig = Bias() >>> copy = clone(orig) >>> copy is orig False >>> copy.damping == orig.damping True
