In the real world, often, we would not be solving some problem for the first time. There would already be some existing solution in place and we would like to improve upon the existing solution. The improvement might come in different flavors; it can be expansion of the solution or simply improvement of the solution on some performance metric.

Interpretation of Area Under the ROC Curve

Background

AUROC is one of the most commonly used metric in binary classification tasks. It stands for Area Under Curve - Receiver Operating Characteristics. It is simply the area under the ROC curve. One way of interpreting AUROC is that it is just the area under the ROC curve obtained by interpolating TPR and FPR at different thresholds. There is also another probabilistic interpretation of AUROC. We will state that and prove why that is the case mathematically.
