AUC stands for the Area Under the Curve and usually refers to the area under the receiver operating characteristic (ROC) curve.

Why to choose AUC over accuracy?
On the other hand, AUC (I'd rather see the entire ROC curve, though) gives you an idea of how the true positive/true negative trade-off works. … With this I mean that models with high AUC can detect a large amount of true positives without losing its ability to detect true negatives and vice-versa. …

Calculate AUC based on TPR and FPR
You can get a reasonable approximation of the AUC by calculating the average height of this graph and then multiplying it by its width ($1$ in this case). … However, in this specific example, we can get the exact value by integrating directly, since it's possible to get TPR as a functión of FPR: $TPR = FPR^{10}$, therefore $AUC = \int_{0}^{1} t^{10}dt = \frac …
