teradataml.hyperparameter_tuner.optimizer.RandomSearch.best_model

DESCRIPTION:
    Returns the best trained model obtained from hyperparameter tuning.
    Note:
        "best_model" is not supported for non-model trainer functions.
 
RETURNS:
    object of trained model.
 
EXAMPLES:
    >>> # Create an instance of the search algorithm called "optimizer_obj" 
    >>> # by referring "__init__()" method.
    >>> # Perform "fit()" method on the optimizer_obj to populate model records.
    >>> # Retrieve the best model.
    >>> optimizer_obj.best_model
