... refers to the ratio of correctly detected tunneled packets to the sum of correctly detected tunneled and incorrectly detected legal packets. Whereas F1 Score is calculated by taking the harmonic average of the precision and recall values, to be able to evaluate these two values as a single value. Besides, ROC curve of the proposed system ...
