InstructTA: Instruction-Tuned Targeted Attack for Large Vision-Language Models

no code implementations4 Dec 2023 Xunguang Wang, Zhenlan Ji, Pingchuan Ma, Zongjie Li, Shuai Wang

Initially, we utilize a public text-to-image generative model to "reverse" the target response into a target image, and employ GPT-4 to infer a reasonable instruction $\boldsymbol{p}^\prime$ from the target response.

Semantic-Aware Adversarial Training for Reliable Deep Hashing Retrieval

1 code implementation IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY 2023 Xu Yuan, Zheng Zhang, Xunguang Wang, Lin Wu

Further, we, for the first time, formulate the formalized adversarial training of deep hashing into a unified minimax optimization under the guidance of the generated mainstay codes.

CgAT: Center-Guided Adversarial Training for Deep Hashing-Based Retrieval

1 code implementation18 Apr 2022 Xunguang Wang, Yiqun Lin, Xiaomeng Li

On the one hand, CgAT generates the worst adversarial examples as augmented data by maximizing the Hamming distance between the hash codes of the adversarial examples and the center codes.

Prototype-supervised Adversarial Network for Targeted Attack of Deep Hashing

1 code implementation CVPR 2021 Xunguang Wang, Zheng Zhang, Baoyuan Wu, Fumin Shen, Guangming Lu

However, deep hashing networks are vulnerable to adversarial examples, which is a practical secure problem but seldom studied in hashing-based retrieval field.
