Warning

Breaking Changes

  • The fit() method for AutoClassifier and AutoRegressor has been renamed to search().

  • AutoClassifier has been renamed to AutoClassificationSearch

  • AutoRegressor has been renamed to AutoRegressionSearch

  • AutoClassificationSearch.results and AutoRegressionSearch.results now is a dictionary with pipeline_results and search_order keys. pipeline_results can be used to access a dictionary that is identical to the old .results dictionary. Whereas, search_order returns a list of the search order in terms of pipeline_id.

  • Pipelines now require an estimator as the last component in component_list. Slicing pipelines now throws an NotImplementedError to avoid returning pipelines without an estimator.
