Testing robustness against unforeseen adversaries
OpenAI's new UAR metric exposes a critical blind spot: your AI model's defenses crumble against attacks it's never seen.
Why it matters
This research addresses a fundamental AI safety and robustness challenge—the gap between tested and real-world adversarial threats. For enterprises deploying classifiers in high-stakes environments, it signals that current robustness claims may be overconfident.

Publisher excerpt: 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…
