Receiver operating characteristic (ROC) curve A receiver operating characteristic curve (ROC) curve displays how well a model can classify binary outcomes. The animation starts with a model that cannot tell one outcome from the other, and the two distributions completely overlap (essentially a random classifier). As the two distributions separate, the ROC curve approaches the left-top corner, and the AUC value of the curve increases. When the model can perfectly separate the two outcomes, the ROC curve forms a right angle and the AUC becomes 1.
