@ -44,8 +44,7 @@ General Parameters
* ``validate_parameters`` [default to ``false``, except for Python, R and CLI interface]
- When set to True, XGBoost will perform validation of input parameters to check whether
a parameter is used or not. The feature is still experimental. It's expected to have
some false positives.
a parameter is used or not.
* ``nthread`` [default to maximum number of threads available if not set]
@ -233,24 +232,21 @@ Parameters for Categorical Feature
These parameters are only used for training with categorical data. See
:doc:`/tutorials/categorical` for more information.
.. note:: These parameters are experimental. ``exact`` tree method is not yet supported.
* ``max_cat_to_onehot``
.. versionadded:: 1.6.0
.. note:: This parameter is experimental. ``exact`` tree method is not yet supported.
- A threshold for deciding whether XGBoost should use one-hot encoding based split for
categorical data. When number of categories is lesser than the threshold then one-hot
encoding is chosen, otherwise the categories will be partitioned into children nodes.
Only relevant for regression and binary classification. Also, ``exact`` tree method is
not supported
* ``max_cat_threshold``
.. versionadded:: 1.7.0
.. note:: This parameter is experimental. ``exact`` tree method is not yet supported.
- Maximum number of categories considered for each split. Used only by partition-based
splits for preventing over-fitting.
