Yansong Ning

Yansong is a second-year M.Phil. student in HKUST(GZ) AI Thrust, supervised by Prof. Hao Liu and Prof. Hui Xiong. Prior to that, he obtained his Bachelor's degree in the School of Data Science at TYUT, supervised by Prof. Li Wang.

His recent research focuses on large language models (LLMs). Specifically, his research goal is to understand and improve the "reasoning capability" of LLMs, guaranteeing their practical applicability in real-world scenarios, e.g., smart city.

[Feb 2025] Thrilled to release DiMA, an LLM-powered ride-hailing assistant deployed on DiDi Chuxing. Thanks for the guidance and support from L Lab!!
