Definition
n. Stands for Receiver Operating Characteristic. A graph that shows how well a test or computer model can tell two things apart. It helps you see the balance between finding the right results and making mistakes.
n. Abbreviation for Receiver Operating Characteristic. A graphical plot that illustrates the diagnostic ability of a binary classifier system as its discrimination threshold is varied. It plots the true positive rate against the false positive rate at various threshold settings.
Examples

“By analyzing the ROC curve, the data scientist determined the optimal threshold for the fraud detection algorithm.”
“A high area under the ROC curve indicates that the model is highly effective at distinguishing between patients with the condition and those without it.”
