Taeckyung Lee

Ph.D. Student, KAIST

About Me

I am a Ph.D. student at KAIST NMSL, under the guidance of Prof. Sung-Ju Lee, with close collaboration with Prof. Jinwoo Shin. I earned my M.S. in Electrical Engineering from KAIST, also under the supervision of Prof. Sung-Ju Lee. I completed my B.S. in Computing at KAIST, graduating Magna Cum Laude.

My research interests include end-user machine learning, including mobile AI, adaptation, and personalization. I am currently focusing on robust and reliable test-time adaptation without any source or labeled data. My recent work includes “AETTA” (CVPR 2024) and “SoTTA” (NeurIPS 2023), which focus on estimating accuracy during test-time adaptation without labeled data and address the challenges of adapting models to noisy data streams, emphasizing the robustness and reliability of test-time adaptation.

As a previous enthusiastic e-sports player, I am also interested in human factors in e-sports.

Analysis on Personality and In-Game Factors in League of Legends (Link)

  • I conducted an in-depth analysis of the personalities and in-game factors of League of Legends players through a collaborative survey with the Professional Spectator YouTube channel.

Few records as a player:

  • Top 0.1% Player (Master tier) in KR Server, League of Legends (2020)
  • Champion in Daejeon Metropolitan City, International e-Sports Festival (IEF), League of Legends (2019)
