Interspeech 2025 oral
I am an M.S. student at the Kim Jaechul Graduate School of AI, KAIST, advised by Prof. Jong Chul Ye in the BISPL lab.
My research centers on the mathematical foundations of generative modeling, particularly diffusion and flow-based models. I am interested in understanding the dynamics of generation and using these insights to develop more efficient learning and sampling methods. I also explore how generative models can be guided to satisfy constraints and solve inverse problems.
