Exploiting the Inherent Limitation of L0 Adversarial Examples

L0 AEs, a category of attacks widely considered by previous works [8,27,34,47]. To defeat attacks based on AEs, both detection and defen-sive techniques attract the research community s attention. Given an input image, the detection system outputs whether it is an AE, so that the target neural network can reject those adversarial inputs.
