F1 score vs AUC, which is the best classification metric?
WebDec 9, 2024 · 22. The classification report is about key metrics in a classification problem. You'll have precision, recall, f1-score and support for each class you're trying to find. The recall means "how many of this class you find over the whole number of element of this class". The precision will be "how many are correctly classified among that class". WebNov 7, 2014 · Interesting aspect. But as far as I understand, F1 score is based on Recall and Precision, whereas AUC/ROC consists of Recall and Specificity. It seems that they are not the same thing. I agree with F score is a point, and ROC is a set of points with different threshold, but I dont think they are the same 'cause of different definition. WebMay 4, 2016 · With a threshold at or lower than your lowest model score (0.5 will work if your model scores everything higher than 0.5), precision and recall are 99% and 100% respectively, leaving your F1 ~99.5%. In this example, your model performed far worse than a random number generator since it assigned its highest confidence to the only negative ... queen\u0027s theatre pantomime
