The - subtree with the largest cost complexity that is smaller than - ``ccp_alpha`` will be chosen. By default, no pruning is performed. See - :ref:`minimal_cost_complexity_pruning` for details. - - .. versionadded:: 0.22 - - Attributes - ---------- - max_features_ : int - The inferred value of max_features. - - n_features_in_ : int - Number of features seen during :term:`fit`. - - .. versionadded:: 0.24 - - feature_names_in_ : ndarray of shape (`n_features_in_`,) - Names of features seen during :term:`fit`. Defined only when `X` - has feature names that are all strings. - - .. versionadded:: 1.0 - - feature_importances_ : ndarray of shape (n_features,) - Return impurity-based feature importances (the higher, the more - important the feature). - - Warning: impurity-based feature importances can be misleading for - high cardinality features (many unique values). See - :func:`sklearn.inspection.permutation_importance` as an alternative. - - n_outputs_ : int - The number of outputs when ``fit`` is performed. - - tree_ : Tree instance - The underlying Tree object. Please refer to - ``help(sklearn.tree._tree.Tree)`` for attributes of Tree object and - :ref:`sphx_glr_auto_examples_tree_plot_unveil_tree_structure.py` - for basic usage of these attributes. - - See Also - -------- - ExtraTreeClassifier : An extremely randomized tree classifier. - sklearn.ensemble.ExtraTreesClassifier : An extra-trees classifier. - sklearn.ensemble.ExtraTreesRegressor : An extra-trees regressor. - - Notes - ----- - The default values for the parameters controlling the size of the trees - (e.g. ``max_depth``, ``min_samples_leaf``, etc.) lead to fully grown and - unpruned trees which can potentially be very large on some data sets.
