How to Utilize Complementary Vision-Text Information for 2D Structure Understanding

Jiancheng Dong, Pengyue Jia, Derong Xu +9

LLMs typically linearize 2D tables into 1D sequences to fit their autoregressive architecture, which weakens row-column adjacency and other layout cues. In contrast, purely visual…

MOSAIC: Composable Safety Alignment with Modular Control Tokens

Jingyu Peng, Hongyu Chen, Jiancheng Dong +5

Safety alignment in large language models (LLMs) is commonly implemented as a single static policy embedded in model parameters. However, real-world deployments often require conte…

Learning a Single Token to Replace Long System Prompts in LLMs

Jiancheng Dong, Pengyue Jia, Jingyu Peng +7

Long system prompts are widely used to steer Large Language Models (LLMs), but repeatedly processing them at inference time is inefficient and consumes valuable context budget. Thi…
