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.
WebApr 15, 2024 · The area under the ROC curve (AUC) value of using nCD64 alone was 0.920, which was higher than that of PCT (0.872), WBC (0.637), and nCD64 combined with WBC (0.906), and a combination of nCD64, WBC, and PCT (0.919) but lower than that of nCD64 combined with PCT (0.924) ( Table 3 and Figure 3 ). 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.
