* - Parameters
-
n_estimator : int
number of trees
max_depth : int,
maximum number of levels in tree
max_features : float, int, or str,
number of features to consider at every split
min_samples_split : float or int,
minimum number of samples required to split a node
min_samples_leaf : float or int,
minimum number of samples required at each leaf node
bootstrap : bool,
method of selecting samples for training each tree
criterion : str,
function to measure the quality of a split
random_state : int, default=42
random_state for model
* - Attributes
-
cv_scores : dict[str, float]
dictionary with cross validation results
feature_names : list[str]
names of all the features that the model saw during training. Is empty if model was not fitted yet.
grid : ConfigurationSpace
hyperparameter tuning grid of the model
model : model object
model with 'fit', 'predict', 'set_params', and 'get_params' method (see sklearn API)
model_name : str
name of the model. Used in loading bars and dictionaries as identifier of the model
model_type : str
kind of estimator (e.g. 'RFC' for RandomForestClassifier)
rCVsearch_results : pd.DataFrame or None
results from randomCV hyperparameter tuning. Is ``None`` if randomCVsearch was not used yet.
train_score : float
train score value
train_time : str
train time in format: "0:00:00" (hours:minutes:seconds)
.. note::
You can use all parameters of the wrapped model when initialising the wrapper class.
