ACTR: Aligning Thoughts and Responses for Multilingual Safety in Reasoning LLMs

Xianhui Zhang, Jian Yu, Chengyu Xie وآخرون · 2026

Ensuring the safety of reasoning large language models (LLMs) across languages is essential for their reliable deployment. However, when exposed to jailbreak attacks in non-high-resource languages, these models may generate unsafe responses even when their reasoning traces identify safety risks. To address this issue, …

DynaForge: Planning-Guided Residual Learning for Dynamic Manipulation Demonstration Generation

Yiyang Jin, Yu Zheng, Xiao He وآخرون · 2026

Dynamic object manipulation is essential for robots operating in real-world environments, yet methods for generating high-quality demonstrations remain limited. Methods designed for static tasks do not readily transfer to dynamic settings. Among dynamic demonstration generators, planning-based methods can fail near con …

PhyVisGen: Physically and Visually High-Fidelity Robotic Manipulation Data Generation

Yu Zheng, Qiyu Feng, Yixin Wu وآخرون · 2026

Large-scale manipulation demonstrations are essential for learning robust visuomotor policies, yet real-world data collection is expensive and difficult to scale. Simulation offers a promising alternative, but physical and visual discrepancies can limit the transferability of synthetic data, particularly for manipulati …
