IGME: Efficient Chained Method Ensemble for Transferable Semantic Segmentation Attacks

Mengqi He, Jing Zhang

The paper proposes IGME, an efficient method that chains attack components to generate transferable adversarial perturbations for semantic segmentation using only a single source m…

Break the Brake, Not the Wheel: Untargeted Jailbreak via Entropy Maximization

Mengqi He, Xinyu Tian, Xin Shen +6

Recent studies show that gradient-based universal image jailbreaks on vision-language models (VLMs) exhibit little or no cross-model transferability, casting doubt on the feasibili…

High-Entropy Tokens as Multimodal Failure Points in Vision-Language Models

Mengqi He, Xinyu Tian, Xin Shen +4

Vision-language models (VLMs) achieve remarkable performance but remain vulnerable to adversarial attacks. Entropy, as a measure of model uncertainty, is highly correlated with VLM…

All Roads Lead to Rome: Incentivizing Divergent Thinking in Vision-Language Models

Xinyu Tian, Shu Zou, Zhaoyuan Yang +3

Recent studies have demonstrated that Reinforcement Learning (RL), notably Group Relative Policy Optimization (GRPO), can intrinsically elicit and enhance the reasoning capabilitie…

More Thought, Less Accuracy? On the Dual Nature of Reasoning in Vision-Language Models

Xinyu Tian, Shu Zou, Zhaoyuan Yang +5

Reasoning has emerged as a pivotal capability in Large Language Models (LLMs). Through Reinforcement Learning (RL), typically Group Relative Policy Optimization (GRPO), these model…

Black Sheep in the Herd: Playing with Spuriously Correlated Attributes for Vision-Language Recognition

Xinyu Tian, Shu Zou, Zhaoyuan Yang +2

Few-shot adaptation for Vision-Language Models (VLMs) presents a dilemma: balancing in-distribution accuracy with out-of-distribution generalization. Recent research has utilized l…
