WebSome metrics are essentially defined for binary classification tasks (e.g. f1_score, roc_auc_score ). In these cases, by default only the positive label is evaluated, assuming by default that the positive class is labelled 1 (though this may be configurable through the pos_label parameter). WebTo use this feature, feed the classifier an indicator matrix, in which cell [i, j] indicates the presence of label j in sample i. Examples: Multilabel classification. 1.12.1.3.
