About Me关于我

I am Feng Xiang, a master's student in Computer Science at Wuhan University and a Research Intern at Alibaba Group.

My research focuses on multimodal large language models and agentic reinforcement learning (including search and memory). Beyond building stronger model reasoning, I am particularly interested in trustworthy reasoning — enabling models to "know what they know and know what they don't", and to proactively gather clearly-sourced evidence to form verifiable reasoning chains. I believe this is essential for deploying LLM/MLLM agents in real-world, high-stakes scenarios. I am also exploring unified multimodal models that incorporate action modalities.

🤝 I am always looking for research collaborations. If you are interested in sharing GPU resources or discussing ideas, feel free to reach out!

我是冯祥武汉大学计算机学院硕士研究生,同时是阿里巴巴集团的研究型实习生。

我目前的研究主要关注多模态大语言模型智能体强化学习(包括搜索和记忆等)。在实现更强的模型推理能力之外,我同时关心可信推理问题——即如何让模型能够"知之为知之,不知为不知",并且可以主动收集来源清晰的证据组成可验证推理链。我认为,这对于将 LLM/MLLM 智能体部署到真实且严肃的场景中具有重要价值。此外,我也在关注融合动作模态的统一多模态模型

🤝 我一直在寻找更多的科研合作。如果您愿意与我共享 GPU 算力或者对我的研究感兴趣想与我讨论,欢迎随时联系我
