Yuanchen Bei
I am a Ph.D. Student at the University of Illinois Urbana-Champaign, advised by Prof. Hanghang Tong.
My research interests mainly include memory for (M)LLM agents, relational data mining, graph learning, and computational social science. In my free time, I am also interested in finance and economics.
