Parameters ---------- X : {array-like, sparse matrix} of shape (n_samples, n_features) Input values. estimator : estimator instance Fitted classifier or a fitted :class:`~sklearn.pipeline.Pipeline` in which the last estimator is a classifier. response_method: {'auto', 'predict_proba', 'decision_function'} Specifies whether to use :term:`predict_proba` or :term:`decision_function` as the target response. If set to 'auto', :term:`predict_proba` is tried first and if it does not exist :term:`decision_function` is tried next. pos_label : str or int, default=None The class considered as the positive class when computing the metrics. By default, `estimators.classes_[1]` is considered as the positive class. Returns ------- y_pred: ndarray of shape (n_samples,) Target scores calculated from the provided response_method and pos_label. pos_label: str or int The class considered as the positive class when computing the metrics. z8Expected 'estimator' to be a binary classifier, but got Nz2The class provided by 'pos_label' is unknown.
