Boundary f1 score

WebThe 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 multi-label case, this is the average of the F1 score of each class with weighting depending on the average parameter.
