skada.DiscriminatorReweight
- skada.DiscriminatorReweight(base_estimator=None, domain_classifier=None)[source]
Discriminator re-weighting pipeline adapter and estimator.
see [1] for details.
- Parameters:
- base_estimatorsklearn estimator, default=None
estimator used for fitting and prediction
- domain_classifiersklearn classifier, optional
Classifier used to predict the domains. If None, a LogisticRegression is used.
- Returns:
- pipelinesklearn pipeline
Pipeline containing the DiscriminatorReweight adapter and the base estimator.
