Yusheng Lu

I am currently a researcher at HiThink Research, working on large language models and recommender systems. I obtained my Ph.D. in Data Science at CityU (Supervisor: Prof. Xiangyu Zhao ) and in Management Science and Engineering at Tongji (Supervisor: Prof. Yongrui Duan ). Before that, I graduated with a Bachelor's degree from CQU in 2019.

My research interests include large language models, sequential recommendation, product pricing, operations research, and applications of machine learning and big data.
