Graduate researcher · Seoul, Korea

Mingyu Kim studies how models learn.

Statistics, language models, and causal reasoning for AI systems we can understand and trust.

I am a graduate student in Statistics and Data Science at Yonsei University. My work connects statistical inference with modern machine learning, with a current focus on diffusion language models and causal machine learning.

Open to research conversations and collaborations.
