	objective objective: typing.Union[str, xgboost.sklearn._SklObjWProto, typing.Callable[[typing.Any, typing.Any], typing.Tuple[numpy.ndarray, numpy.ndarray]], NoneType] Specify the learning task and the corresponding learning objective or a custom objective function to be used. For custom objective, see :doc:`/tutorials/custom_metric_obj` and :ref:`custom-obj-metric` for more information, along with the end note for function signatures.	'reg:squarederror'
	base_score base_score: typing.Union[float, typing.List[float], NoneType] The initial prediction score of all instances, global bias.	None
	booster	None
	callbacks callbacks: typing.Optional[typing.List[xgboost.callback.TrainingCallback]] List of callback functions that are applied at end of each iteration. It is possible to use predefined callbacks by using :ref:`Callback API `. .. note:: States in callback are not preserved during training, which means callback objects can not be reused for multiple training sessions without reinitialization or deepcopy. .. code-block:: python for params in parameters_grid: # be sure to (re)initialize the callbacks before each run callbacks = [xgb.callback.LearningRateScheduler(custom_rates)] reg = xgboost.XGBRegressor(**params, callbacks=callbacks) reg.fit(X, y)	None
	colsample_bylevel colsample_bylevel: typing.Optional[float] Subsample ratio of columns for each level.	None
	colsample_bynode colsample_bynode: typing.Optional[float] Subsample ratio of columns for each split.	None
	colsample_bytree colsample_bytree: typing.Optional[float] Subsample ratio of columns when constructing each tree.	None
	device device: typing.Optional[str] .. versionadded:: 2.0.0 Device ordinal, available options are `cpu`, `cuda`, and `gpu`.	None
	early_stopping_rounds early_stopping_rounds: typing.Optional[int] .. versionadded:: 1.6.0 - Activates early stopping. Validation metric needs to improve at least once in every early_stopping_rounds round(s) to continue training. Requires at least one item in eval_set in :py:meth:`fit`. - If early stopping occurs, the model will have two additional attributes: :py:attr:`best_score` and :py:attr:`best_iteration`. These are used by the :py:meth:`predict` and :py:meth:`apply` methods to determine the optimal number of trees during inference. If users want to access the full model (including trees built after early stopping), they can specify the `iteration_range` in these inference methods. In addition, other utilities like model plotting can also use the entire model. - If you prefer to discard the trees after `best_iteration`, consider using the callback function :py:class:`xgboost.callback.EarlyStopping`. - If there's more than one item in eval_set, the last entry will be used for early stopping. If there's more than one metric in eval_metric, the last metric will be used for early stopping.	None
	enable_categorical enable_categorical: bool See the same parameter of :py:class:`DMatrix` for details.	False
	eval_metric eval_metric: typing.Union[str, typing.List[typing.Union[str, typing.Callable]], typing.Callable, NoneType] .. versionadded:: 1.6.0 Metric used for monitoring the training result and early stopping. It can be a string or list of strings as names of predefined metric in XGBoost (See :doc:`/parameter`), one of the metrics in :py:mod:`sklearn.metrics`, or any other user defined metric that looks like `sklearn.metrics`. If custom objective is also provided, then custom metric should implement the corresponding reverse link function. Unlike the `scoring` parameter commonly used in scikit-learn, when a callable object is provided, it's assumed to be a cost function and by default XGBoost will minimize the result during early stopping. For advanced usage on Early stopping like directly choosing to maximize instead of minimize, see :py:obj:`xgboost.callback.EarlyStopping`. See :doc:`/tutorials/custom_metric_obj` and :ref:`custom-obj-metric` for more information. .. code-block:: python from sklearn.datasets import load_diabetes from sklearn.metrics import mean_absolute_error X, y = load_diabetes(return_X_y=True) reg = xgb.XGBRegressor( tree_method="hist", eval_metric=mean_absolute_error, ) reg.fit(X, y, eval_set=[(X, y)])	None

Used only by partition-based splits for preventing over-fitting. Also, `enable_categorical` needs to be set to have categorical feature support. See :doc:`Categorical Data ` and :ref:`cat-param` for details.	None
	max_cat_to_onehot max_cat_to_onehot: Optional[int] .. versionadded:: 1.6.0 .. note:: This parameter is experimental A threshold for deciding whether XGBoost should use one-hot encoding based split for categorical data.
