Learning Modal-Mixed Chain-of-Thought Reasoning with Latent Embeddings

Yifei Shao, Kun Zhou, Ziming Xu +5

We study how to extend chain-of-thought (CoT) beyond language to better handle multimodal reasoning. While CoT helps LLMs and VLMs articulate intermediate steps, its text-only form…

Ability Transfer and Recovery via Modularized Parameters Localization

Songyao Jin, Kun Zhou, Wenqi Li +2

Large language models can be continually pre-trained or fine-tuned to improve performance in specific domains, languages, or skills, but this specialization often degrades other ca…

Learning Plug-and-play Memory for Guiding Video Diffusion Models

Selena Song, Ziming Xu, Zijun Zhang +4

Diffusion Transformer(DiT) based video generation models have recently achieved impressive visual quality and temporal coherence, but they still frequently violate basic physical l…

Auto-scaling Continuous Memory for GUI Agent

Wenyi Wu, Kun Zhou, Ruoxin Yuan +4

We study how to endow GUI agents with scalable memory that help generalize across unfamiliar interfaces and long-horizon tasks. Prior GUI agents compress past trajectories into tex…

Backdoor Attribution: Elucidating and Controlling Backdoor in Language Models

Miao Yu, Zhenhong Zhou, Moayad Aloqaily +5

Fine-tuned Large Language Models (LLMs) are vulnerable to backdoor attacks through data poisoning, yet the internal mechanisms governing these attacks remain a black box. Previous…

Activation Control for Efficiently Eliciting Long Chain-of-thought Ability of Language Models

Zekai Zhao, Qi Liu, Kun Zhou +4

Despite the remarkable reasoning performance, eliciting the long chain-of-thought (CoT) ability in large language models (LLMs) typically requires costly reinforcement learning or…
