Yeachan Park

Yeachan Park is an Assistant Professor in the Department of Mathematics and Statistics at Sejong University, South Korea, since 2025, following a postdoctoral fellowship at Korea Institute for Advanced Study (KIAS) from 2022-2025.

Education:

• Ph.D., Seoul National University (2022)
• B.S., Pohang University of Science and Technology (2015)

His research centers on low-level computer vision and machine learning theory, with major contributions in neural network expressivity, loss surface geometry, computer arithmetic implementations (floating/fixed-point), mathematical language models, and learning dynamics. This work bridges theoretical mathematics with practical deep learning applications through rigorous mathematical frameworks.

Recent publications (2022-2025) demonstrate consistent focus on mathematical foundations of deep learning, spanning computer vision (image deraining), neural network theory (expressivity under finite precision), and learning dynamics (grokking acceleration). The research exhibits strong interdisciplinary integration of numerical analysis, theoretical computer science, and image processing.
