In this paper, we focus on the scenario where there is a mismatch in the threat model assumed by the defense during training, and the actual capabilities of the adversary at test time. We ask the question: if the learner trains against a specific \"source\" threat model, when can we expect robustness to generalize to a stronger unknown \"target\" threat model during test-time?
