AUC score is area under the ROC curve which is different F1 score which is harmonic mean of precision and recall scores.
WebOct 19, 2024 · F1 Score Formula (Image Source: Author) Having a precision or recall value as 0 is not desirable and hence it will give us the F1 score of 0 (lowest). On the other hand, if both the precision and recall … WebBF (Boundary F1) Score The BF score measures how close the predicted boundary of an object matches the ground truth boundary. The BF score is defined as the harmonic mean (F1-measure) of the …
WebWhen you have a multiclass setting, the average parameter in the f1_score function needs to be one of these: 'weighted' 'micro' 'macro' The first one, 'weighted' calculates de F1 score for each class independently but when it adds them together uses a weight that depends on the number of true labels of each class: WebThe F1-score is a great way to compare the performance of multiple classifiers. When choosing between multiple models, all with varying values of precision and/or recall, it may be used to determine which one produces the 'best' results for the problem at hand.
