About
I am a Ph.D. candidate in School of Electrical and Electronic Engineering at Yonsei University.
My research interests span a wide spectrum of machine learning and computer vision, mainly focusing on efficient machine learning (network quantization, network architecture search, knowledge distillation), image matching (semantic correspondence), and image restoration (super-resolution).
Education
- Joint course of M.S./Ph.D degrees in School of Electrical and Electronic Engineering, Yonsei University, Seoul, Korea (Mar. 2018 - Aug. 2024 (expected)).
- Supervised by Prof. Bumsub Ham in Computer Vision Lab.
- B.S. in School of Electrical and Electronic Engineering, Yonsei University, Seoul, Korea (Mar. 2012 - Feb. 2018).
