Web10 Aug 2024 · The ROC is a graph which maps the relationship between true positive rate (TPR) and the false positive rate (FPR), showing the TPR that we can expect to receive for a given trade-off with FPR. The AUC score is the area under this ROC curve, meaning that the resulting score represents in broad terms the model's ability to predict classes correctly.

Web31 Oct 2024 · ROC is a probability curve, and AUC represents the degree or measure of separability. It tells how much model is capable of distinguishing between classes. Higher the AUC, better the model is at predicting 0s as 0s and 1s as 1s. By analogy, Higher the AUC, better the model is at distinguishing between patients with the disease and no disease.
