SEER: Backdoor Detection for Vision-Language Models through Searching Target Text and Image Trigger Jointly

AAAI 2024technical

This paper proposes SEER, a novel backdoor detection algorithm for vision-language models, addressing the gap in the literature on multi-modal backdoor detection. While backdoor detection in single-modal models has been well studied, the investigation of such defenses in multi-modal models remains l…

Most and Least Retrievable Images in Visual-Language Query Systems

ECCV 2022poster

"This is the first work to introduce the Most Retrievable Image(MRI) and Least Retrievable Image(LRI) concepts in modern text-to-image retrieval systems. An MRI is associated with and thus can be retrieved by many unrelated texts, while an LRI is disassociated from and thus not retrievable by relate…

CLEAR: Clean-Up Sample-Targeted Backdoor in Neural Networks

ICCV 2021poster

The data poisoning attack has raised serious security concerns on the safety of deep neural networks since it can lead to neural backdoor that misclassifies certain inputs crafted by an attacker. In particular, the sample-targeted backdoor attack is a new challenge. It targets at one or a few specif…
