Hierarchical Safety Realignment: Lightweight Restoration of Safety in Pruned Large Vision-Language Models

ACL 2025finding

With the increasing size of Large Vision-Language Models (LVLMs), network pruning techniques aimed at compressing models for deployment in resource-constrained environments have garnered significant attention. However, we observe that pruning often leads to a degradation in safety performance. To ad…

NLSR: Neuron-Level Safety Realignment of Large Language Models Against Harmful Fine-Tuning

AAAI 2025technical

The emergence of fine-tuning-as-a-service has revealed a new vulnerability in large language models (LLMs). A mere handful of malicious data uploaded by users can subtly manipulate the fine-tuning process, leading to a compromised alignment state. Existing methods to counteract fine-tuning attacks t…

Towards Benchmarking and Assessing Visual Naturalness of Physical World Adversarial Attacks

CVPR 2023poster

Physical world adversarial attack is a highly practical and threatening attack, which fools real world deep learning systems by generating conspicuous and maliciously crafted real world artifacts. In physical world attacks, evaluating naturalness is highly emphasized since human can easily detect an…
