Sangwu Park I'm an M.S. student in Data Science at KAIST, where I'm advised by Prof. Chanyoung Park at the Data Science and Artificial Intelligence Lab (DSAIL). Previously, I received my B.S. in Applied Statistics from Chung-Ang University. |
|
ResearchI'm interested in Vision-Language-Action (VLA) models and Agentic AI, with a broader goal of building fully autonomous embodied AI and agents. Representative papers are highlighted. |
