Unforeseen Attack Robustness (UAR)
We’ve developed a method to assess whether a neural network classifier can reliably defend against adversarial attacks not seen during training.
Our method yields a new metric, UAR (Unforeseen Attack Robustness), which evaluates the robustness of a single model against an unanticipated attack, and highlights the need to measure performance across a more diverse range of unforeseen attacks.
