I am an assistant professor working at Chung-Ang University. Before this, I did my postdoc with Prof. Nicolò Cesa-Bianchi at Università degil Studi di Milano, Prof. Komiyama Junpei at NYU, and Prof. Kwang-Sung Jun at the University of Arizona. I got my Ph.D. in the Department of Mathematical Science at KAIST (Korea Advanced Institute of Science and Technology) with the advisor Wanmo Kang.
My research interests lie in statistical machine-learning problems, such as
- Reinforcement learning (bandit)
- High-dimensional bandits (sparse, bilinear, etc.)
- Best arm identification
- Generalization bounds (PAC-Bayes bound)
- Generative model (GAN, VAE)
- Other probabilistic tools (Stochastic PDE, Random Matrix Theory, etc......)
