Yaorui Shi

I am a 3rd year PhD student at the University of Science and Technology of China (USTC), under the supervision of Prof. An Zhang and Xiang Wang.

My research interests include large reasoning models, reinforcement learning and agentic memory. I am particularly interested in developing innovative AI algorithms and applying them to solve real-world problems.

Before joining USTC, I received my Bachelor’s degree in Computer Science from XJTU’s Young Gifted Class (少年班). Currently, I am a research intern at Meituan LongCat Team, where I lead projects about multi-modal agentic RL.

I am open to research collaborations and internship opportunities, especially those related to experimental memory management / agentic self-evolving.

Look Back to Reason Forward: Revisitable Memory for Long-Context LLM Agents

Yaorui Shi, Yuxin Chen, Siyuan Wang, and 5 more authors

In International Conference on Learning Representations (ICLR), 2025

Abs arXiv PDF Code

Large language models struggle with long-context question answering when relevant evidence is dispersed across millions of tokens. We propose ReMemR1, which incorporates memory retrieval capabilities into the memory update process, enabling agents to selectively revisit historical memories for non-linear reasoning.
Search and Refine During Think: Facilitating Knowledge Refinement for Improved Retrieval-Augmented Reasoning

Yaorui Shi, Sihang Li, Chang Wu, and 5 more authors

In Advances in Neural Information Processing Systems (NeurIPS), 2025

Abs arXiv PDF Code Website

We introduce AutoRefine, a novel framework that enhances retrieval-augmented reasoning by integrating autonomous knowledge refinement into the reasoning process. AutoRefine dynamically refines retrieved documents to improve retrieval quality and reduce hallucination, enabling more reliable and contextually relevant reasoning.
SciLitLLM: How to Adapt LLMs for Scientific Literature Understanding

Sihang Li, Jin Huang, Jiaxi Zhuang, and 7 more authors

In International Conference on Learning Representations (ICLR), 2025

Abs arXiv PDF Code Website

We address challenges in using large language models for scientific document comprehension by proposing a hybrid strategy that integrates continual pre-training with supervised fine-tuning to infuse scientific knowledge while improving task-specific instruction-following abilities.
