Hi,
I don’t understand why in the correction of the ExM6.03, the validation curve is done with the data_train instead of the whole data?
train_scores, test_scores = validation_curve( adaboost, data_train, target_train, param_name=“n_estimators”, param_range=param_range, scoring=“neg_mean_absolute_error”, n_jobs=2)
Thanks in advance,
