Counterfactual-based Saliency Map: Towards Visual Contrastive Explanations for Neural Networks

ICCV 2023poster

Explaining deep models in a human-understandable way has been explored by many works that mostly explain why an input causes a corresponding prediction (ie., Why P?). However, seldom they could handle those more complex causal questions like "why P rather than Q?" and "why one is P while another is…

Towards Transferable Targeted Adversarial Examples

CVPR 2023poster

Transferability of adversarial examples is critical for black-box deep learning model attacks. While most existing studies focus on enhancing the transferability of untargeted adversarial attacks, few of them studied how to generate transferable targeted adversarial examples that can mislead models…

Feature Importance-Aware Transferable Adversarial Attacks

ICCV 2021poster

Transferability of adversarial examples is of central importance for attacking an unknown model, which facilitates adversarial attacks in more practical scenarios, e.g., blackbox attacks. Existing transferable attacks tend to craft adversarial examples by indiscriminately distorting features to degr…
