Jaehyung Kim

I am a 4th year Ph.D. student at ALIN Lab, advised by Prof. Jinwoo Shin at Korea Advanced Institute of Science and Technology (KAIST). I received an M.S. in Electrical Engineering (Feb. 2019) and a B.S. in Mathematics (Feb. 2017) in KAIST. 

My research goal is to build an effective machine learning (ML) pipeline to tackle various real-world problems. To this end, I have been focused on developing improved ML algorithms for applying it to more practical and challenging scenarios, e.g., low-resource, class-imbalanced, and semi-supervised learning. Recently, I'm interested in more extensive topics to achieve the goal, such as data-centric ML or human-in-loop ML.
