Fast adversarial training using fgsm
WebOct 22, 2024 · High cost of training time caused by multi-step adversarial example generation is a major challenge in adversarial training. Previous methods try to reduce the computational burden of adversarial training using single-step adversarial example generation schemes, which can effectively improve the efficiency but also introduce the … WebNov 3, 2024 · FAT tries to eliminate this issue by using FGSM as its adversarial example generator. However, this simplification 1) may lead to catastrophic overfitting [2, 41], and 2) is not easy to generalize to all types of adversarial training as FGSM is designed explicitly for \(\ell _\infty \) attacks.
