From: EPASAD: ellipsoid decision boundary based Process-Aware Stealthy Attack Detector
Comparison of PASAD and EPASAD over the pump-flow sensor (F_PU7) of C-town dataset, collected during 14 different attacks where PASAD fails to detect the abnormality induced during the \(5\text{th}\) attack, and EPASAD is able to detect it. The green measurements are normal measurements used for training. The black and red measurements are normal, and attack measurements are used for testing. Note that the order of each subfigure has the same definition as Figs. 4 and 5
