Hello, I’m Qiming Li (启明 李), a master student of HIT-SCIR under the supervision of Prof.Xiaocheng Feng and Prof.Bing Qin. I am currently working as a research intern at Meituan Longcat Team. Previously, I’m a visiting student of THUNLP under the supervision of Prof.Zhiyuan Liu, and a research assistant of HKUNLP under the supervision of Postdoc.Xiachong Feng and Prof.Lingpeng Kong. My research interests focus on Large Vision-Language Models (LVLMs), including OPD, Coding & Web Agent and Hallucination.
