Attention Deficit is Ordered! Fooling Deformable Vision Transformers with Collaborative Adversarial Patches

no code implementations21 Nov 2023 Quazi Mishkatul Alam, Bilel Tarchoun, Ihsen Alouani, Nael Abu-Ghazaleh

The latest generation of transformer-based vision models has proven to be superior to Convolutional Neural Network (CNN)-based models across several vision tasks, largely attributed to their remarkable prowess in relation modeling.

Jedi: Entropy-based Localization and Removal of Adversarial Patches

no code implementations CVPR 2023 Bilel Tarchoun, Anouar Ben Khalifa, Mohamed Ali Mahjoub, Nael Abu-Ghazaleh, Ihsen Alouani

Jedi tackles the patch localization problem from an information theory perspective; leverages two new ideas: (1) it improves the identification of potential patch regions using entropy analysis: we show that the entropy of adversarial patches is high, even in naturalistic patches; and (2) it improves the localization of adversarial patches, using an autoencoder that is able to complete patch regions from high entropy kernels.
