Boosting Adversarial Transferability via Fusing Logits of Top-1 Decomposed Feature

1 code implementation2 May 2023 Juanjuan Weng, Zhiming Luo, Dazhen Lin, Shaozi Li, Zhun Zhong

Recent research has shown that Deep Neural Networks (DNNs) are highly vulnerable to adversarial samples, which are highly transferable and can be used to attack other unknown black-box models.

Logit Margin Matters: Improving Transferable Targeted Adversarial Attack by Logit Calibration

2 code implementations7 Mar 2023 Juanjuan Weng, Zhiming Luo, Zhun Zhong, Shaozi Li, Nicu Sebe

In this work, we provide a comprehensive investigation of the CE loss function and find that the logit margin between the targeted and untargeted classes will quickly obtain saturation in CE, which largely limits the transferability.
