Webrecall_score (y_true, y_pred, *, labels = None, pos_label = 1, average = 'binary', sample_weight = None, zero_division = 'warn') [source] ¶. Compute the recall. The recall is the ratio tp / (tp + fn) where tp is the number of true positives and fn the number of false negatives. The recall is intuitively the ability of the classifier to find all the positive samples. WebCompute Area Under the Receiver Operating Characteristic Curve (ROC AUC) from prediction scores. Note: this implementation is restricted to the binary classification task or multilabel classification task in label indicator format. Read more in the User Guide.

I suspect the difference is that in multi-class problems the classes are mutually exclusive, whereas for multi-label problems each label represents a different classification task, but the tasks are somehow related (so there is a benefit in tackling them together rather than separately).
