I am a Ph.D. candidate at X-Lance Lab, Shanghai Jiao Tong University, under supervision of Prof. Kai Yu, majoring in computer science and technology. Before that, I received my B.S. degree from the Department of Automation, Tsinghua University in 2020.

My research interest focuses on text-rich visual UI interaction. Currently, I’m working on constrution of realistic, complex interaction benchmark for GUI interaction. I’m also studying how to design smarter GUI agents with reinforcement learning (RL) and large language models (LLM), or by combining both.

Large Language Models Are Semi-Parametric Reinforcement Learning Agents

Danyang Zhang, Lu Chen, Situo Zhang, Hongshen Xu, Zihan Zhao, Kai Yu
NeurIPS 2023 | Code

• We designed Rememberer, a novel evolvable LLM-based agent framework, by equipping the LLM with a long-term experience memory, so as to enable the LLM to exploit the interaction experiences to improve performance.
• We proposed Reinforcement Learning with Experience Memory (RLEM) to update the memory, so that the agent can learn from both success and failure, and evolve its capability without fine-tuning LLM parameters.
• Rememberer demonstrates superior performance and robustness on both WebShop and WikiHow task set.
