WebThe final estimator is an ensemble of n_cv fitted classifier and calibrator pairs, where n_cv is the number of cross-validation folds. The output is the average predicted probabilities of all pairs. If False, cv is used to compute unbiased predictions, via cross_val_predict, which are then used for calibration.
