Adversarial Examples as an Input-Fault Tolerance Problem

Angus Galloway, Anna Golubeva, Graham W. Taylor

Abstract: We analyze the adversarial examples problem in terms of a model's fault tolerance with respect to its input. Whereas previous work focuses on arbitrarily strict threat models, i.e., $\epsilon$-perturbations, we consider arbitrary valid inputs and propose an information-based characteristic for evaluating tolerance to diverse input faults.
