lenskit.flexmf.FlexMFExplicitScorer
===================================

.. py:class:: lenskit.flexmf.FlexMFExplicitScorer(config = None, **kwargs)
   :canonical: lenskit.flexmf._explicit.FlexMFExplicitScorer

   Bases: :py:obj:`lenskit.flexmf._base.FlexMFScorerBase`


   Explicit-feedback rating prediction with FlexMF.  This realizes a biased
   matrix factorization model (similar to :class:`lenskit.als.BiasedMF`)
   trained with PyTorch.

   :Stability: Experimental


   .. py:attribute:: global_bias
      :type:  float


   .. py:attribute:: config
      :type:  FlexMFExplicitConfig

      The component configuration object.  Component classes that support
      configuration **must** redefine this attribute with their specific
      configuration class type, which can be a Python dataclass or a Pydantic
      model class.


   .. py:method:: create_trainer(data, options)

      Create a model trainer to train this model.



   .. py:method:: score_items(users, items)

      Score for users and items, after resolivng them and limiting to known
      users and items.
