Juyong Lee

I am a PhD(/MS int.) candidate at KAIST, advised by Kimin Lee. I received a B.S. degree with a double major in both mathematics and computer science/engineering at POSTECH. I have an experience as an exchange student at Stanford.

My recent study focuses on building autonomous agents with LLM and RL for digital device control.

	Learning to Contextualize Web Pages for Enhanced Decision Making by LLM Agents Dongjun Lee, Juyong Lee, Kyuyoung Kim, Jihoon Tack, Jinwoo Shin, Yee Whye Teh, Kimin Lee ICLR 2025 project / paper A novel framework of training a contextualization module to help the decision-making of LLM agents achieves the super-human performance in the WebShop benchmark.
	MobileSafetyBench: Evaluating Safety of Autonomous Agents in Mobile Device Control Juyong Lee, Dongyoon Hahm, June Suk Choi, W. Bradley Knox, Kimin Lee Preprint* project / paper / code We propose a new benchmark for evaluating the safety and helpfulness of agents, with extensive analysis of the shortcomings of frontier LLM agents in mobile device control.
	B-MoCA: Benchmarking Mobile Device Control Agents across Diverse Configurations Juyong Lee, Taywon Min, Minyong An, Dongyoon Hahm, Haeone Lee, Changyeon Kim, Kimin Lee ICLR 2024 Workshop: GenAI4DM (spotlight presentation) project / paper / code A novel benchmark that can serve as a unified testbed for mobile device control agents on performing practical daily tasks across diverse device configurations.
