I’m currently a master student at Fudan University at the School of Computer Science of Fudan University. I am a member of Fudan NLP Lab, advised by Prof. Xuanjing Huang (黄萱菁) and Associate Prof. Tao Gui(桂 韬). I got my bachelor’s degree from Tongji University, advised by Associate Prof. Dawei Cheng.
My research interest mainly lies in Multimodal reasoning, LLM Agent, Reinforcement Learning and Efficient AI.

Memory in the Age of AI Agents: A Survey
Yuyang Hu†, Shichun Liu†, Yanwei Yue†, Guibin Zhang†, Boyang Liu,etc.
- Memory serves as the cornerstone of foundation model-based agents, underpinning their ability to perform long-horizon reasoning, adapt continually, and interact effectively with complex environments. We provide a comprehensive overview through three unified lenses: Forms, Functions, and Dynamics.

Unlocking the Essence of Beauty: Advanced Aesthetic Reasoning with Relative-Absolute Policy Optimization
Boyang Liu†, Yifan Hu†, Senjie Jin†, Shihan Dou, Gonglei Shi, Jie Shao, Tao Gui, Xuanjing Huang
- We propose Aes-R1, a comprehensive aesthetic reasoning framework with reinforcement learning (RL). Concretely, Aes-R1 integrates a pipeline, AesCoT, to construct and filter high-quality chain-of-thought aesthetic reasoning data used for cold-start. After teaching the model to generate structured explanations prior to scoring, we then employ the Relative-Absolute Policy Optimization (RAPO), a novel RL algorithm that jointly optimizes absolute score regression and relative ranking order, improving both per-image accuracy and cross-image preference judgments. Aes-R1 enables MLLMs to generate grounded explanations alongside faithful scores, thereby enhancing aesthetic scoring and reasoning in a unified framework.

Masrouter: Learning to route llms for multi-agent systems
Yanwei Yue†, Guibin Zhang†, Boyang Liu†, Guancheng Wan, Kun Wang, Dawei Cheng, Yiyan Qi
- We first introduce the problem of Multi-Agent System Routing(MASR), which integrates all components ofMAS into a unified routing framework. Toward this goal, we propose MasRouter, the first high-performing, cost-effective, and inductive MASR solution. MasRouter employs collaboration mode determination, role allocation, and LLM routing through a cascaded controller network, progressively constructing a MAS that balances effectiveness and efficiency.
