PIP: Detecting Adversarial Examples in Large Vision-Language Models via Attention Patterns of Irrelevant Probe Questions

Posted by dbos Peking

Kavli Affiliate: Jiansheng Chen | First 5 Authors: Yudong Zhang, Ruobing Xie, Jiansheng Chen, Xingwu Sun, Yu Wang | Summary: Large Vision-Language Models (LVLMs) have demonstrated their powerful multimodal capabilities. However, they also face serious safety problems, as adversaries can induce robustness issues in LVLMs through the use of well-designed adversarial examples. Therefore, LVLMs are […]

Neutron stars in the bumblebee theory of gravity

Posted by dbos Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Peixiang Ji, Zhuhai Li, Lirui Yang, Rui Xu, Zexin Hu | Summary: Recently, theoretical studies on the bumblebee gravity model, a nonminimally-coupled vector-tensor theory that violates the Lorentz symmetry, have flourished, with a simultaneous increase in the utilization of observations to impose constraints. The static spherical solutions […]

Qihoo-T2X: An Efficiency-Focused Diffusion Transformer via Proxy Tokens for Text-to-Any-Task

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Ao Ma, Jiasong Feng, Dawei Leng, Yuhui Yin | Summary: The global self-attention mechanism in diffusion transformers involves redundant computation due to the sparse and redundant nature of visual information, and the attention map of tokens within a spatial window shows significant similarity. To address […]

Map-level baryonification: Efficient modelling of higher-order correlations in the weak lensing and thermal Sunyaev-Zeldovich fields

Posted by Chicago

Kavli Affiliate: Chihway Chang | First 5 Authors: Dhayaa Anbajagane, Shivam Pandey, Chihway Chang, , | Summary: Semi-analytic methods can generate baryon-corrected fields from N-body simulations (“baryonification”) and are rapidly becoming a ubiquitous tool in modeling structure formation on non-linear scales. We extend this formalism to consistently model the weak lensing and thermal Sunyaev-Zeldovich (tSZ) […]
