WebJul 22, 2014 · AUC applies to binary classifiers that have some notion of a decision threshold internally. For example logistic regression returns positive/negative depending on whether the logistic function is greater/smaller than a threshold, usually 0.5 by default. When you choose your threshold, you have a classifier. You have to choose one. WebAug 18, 2024 · What Is AUC? The AUC is the area under the ROC Curve. This area is always represented as a value between 0 to 1 (just as both TPR and FPR can range from 0 to 1), and we essentially want to maximize this area so that we can have the highest TPR and lowest FPR for some threshold.
