JiHyuk Byun

I am an M.S. student in Artificial Intelligence at Yonsei University, advised by Prof. Seon Joo Kim.

My research focuses on intelligent visual systems, especially agentic AI, 3D vision, vision-language models, and multimodal learning. I am interested in developing models and evaluations that connect visual understanding with practical decision-making.

Research interests: Agentic AI, 3D Vision, Vision-Language Models (VLMs), and Multimodal Learning.
