WebSep 4, 2024 · In macro-averaging, we first reduce each of the k confusion matrices into a desired metric, and then average out the k scores into a single score. In macro-average, we first calculate a... Webaverage {‘micro’, ‘macro’, ‘samples’, ‘weighted’} or None, default=’macro’ If None, the scores for each class are returned. Otherwise, this determines the type of averaging performed on the data. Note: multiclass ROC AUC currently only handles the ‘macro’ and ‘weighted’ averages.
