Hoyoung Kim

I am a graduate student in the Graduate School of Artificial Intelligence at POSTECH and a member of the Machine Learning Laboratory, advised by Prof. Jungseul Ok.

My research interest lies in investigating diverse feedback mechanisms in machine learning, spanning from human-annotations to self-improvement, with the goal of the efficient evolution of artificial intelligence.

If you are interested in my research projects, please feel free to contact me via cskhy16@postech.ac.kr.
