We are a research group headed by Prof. Jy-yong Sohn in the Department of Applied Statistics at Yonsei University.
We focus on research topics in the intersection of information theory and machine learning. More broadly, we delve into various topics in machine learning and artificial intelligence, using mathematical tools from information theory, optimization, learning theory, and probability & statistics. Current research topics include
Foundation Models (including Large Language Models)
Representation Learning
Efficient Machine Learning
For the details of each research topic, please check this page. If you are interested in joining our group, please contact me.
