Yeah. AUC is calculated after calculating the sensitivity vs specificity plot which is know to be used for classification tasks. We want to calculate the classification stats for each threshold from 0 to 1 eg 0, 0.1 etc. Then we plot the TPR and FPR on the plot. Once we plot, we can calculate the area under curve (AUC). Higher the AUC better. It ranges between 0 and 1.
