Minhyuk An

I'm currently a master's student in the department of Artificial Intelligence at Yonsei University. I am working at the Soft Computing Laboratory (SCLab) and am fortunate to be advised by Sung-Bae Cho.
Previously, I graduated from Inha University with B.S. in the department of Information and Communication Engineering and was advised by Sungeun Hong and Hakil Kim.
