WitrynaThe relative contribution of precision and recall to the F1 score are equal. The formula for the F1 score is: F1 = 2 * (precision * recall) / (precision + recall) In the multi-class and … Witryna17 lis 2024 · A macro-average f1 score is not computed from macro-average precision and recall values. Macro-averaging computes the value of a metric for each class and returns an unweighted average of the individual values. Thus, computing f1_score with average='macro' computes f1 scores for each class and returns the average of those …
