WebbThis module is a simple wrapper to get the task specific versions of this metric, which is done by setting the task argument to either 'binary', 'multiclass' or multilabel. See the documentation of BinaryAUROC, MulticlassAUROC and MultilabelAUROC for the specific details of each argument influence and examples. Legacy Example: >>>. WebbAll metrics in a compute group share the same metric state and are therefore only different in their compute step e.g. accuracy, precision and recall can all be computed from the true positives/negatives and false positives/negatives. By default, this argument is True which enables this feature.
