Generalizable Adversarial Examples Detection Based on Bi-model Decision Mismatch

no code implementations21 Feb 2018 João Monteiro, Isabela Albuquerque, Zahid Akhtar, Tiago H. Falk

Non-linear binary classifiers trained on top of our proposed features can achieve a high detection rate (>90%) in a set of white-box attacks and maintain such performance when tested against unseen attacks.
