Hyunwook Choi

I'm an M.S./Ph.D. student in Artificial Intelligence at KAIST AI, advised by Professor Seungryong Kim. My research lies in computer vision, with a focus on World Models, Auto-Regressive Video Generation, and 4D Representations.

My current work explores video generation models that grounds world states and enable controllable and real-time video generation.
