Mitigating Factual Hallucination in Large Reasoning Models via Mixed-Mode Advantage Regularization

Kaishen Wang, Tong Zheng, Xuehao Cui +3

Large reasoning models (LRMs) improve language model capabilities by generating explicit thinking traces before final answers. In factuality-oriented question answering (QA), such…

Learning from Self-Debate: Preparing Reasoning Models for Multi-Agent Debate

Chenxi Liu, Yanshuo Chen, Ruibo Chen +3

The reasoning abilities of large language models (LLMs) have been substantially improved by reinforcement learning with verifiable rewards (RLVR). At test time, collaborative reaso…

Improving Text-to-Image Generation with Input-Side Inference-Time Scaling

Ruibo Chen, Jiacheng Pan, Heng Huang +1

Recent advances in text-to-image (T2I) generation have achieved impressive results, yet existing models often struggle with simple or underspecified prompts, leading to suboptimal…

Leave No TRACE: Black-box Detection of Copyrighted Dataset Usage in Large Language Models via Watermarking

Jingqi Zhang, Ruibo Chen, Yingqing Yang +3

Large Language Models (LLMs) are increasingly fine-tuned on smaller, domain-specific datasets to improve downstream performance. These datasets often contain proprietary or copyrig…
