Ziran Yang | 杨子然

I am currently an undergraduate student majoring in Artificial Intelligence at Yuanpei College, Peking University. I am now guided by Prof. Yaodong Yang, while I am also fortunate to be a member of the Tong Class (a special pivot AI program led by Prof. Song-Chun Zhu). I am also fortunate to be advised by Prof. Zhiting Hu at UCSD and Prof. Jiawei Zhou at Stony Brook University.

Research Overview

My research focuses on advancing foundation models beyond (semi-)supervised pretraining and imitation learning by integrating advanced algorithms from reinforcement learning and multi-agent systems, alongside principled insights from game theory and information theory, to better understand and control the behavior of complex AI systems, particularly large language and multimodal models. This includes exploring game equilibria in multi-agent settings, measuring and decomposing uncertainty, and analyzing how information flows in multimodal models to strengthen their reasoning skills and overall performance. Which is especially pertinent in the context of trustworthy AI, scalable oversight, reasoning, and LLM agents.
