About

I am a Ph.D. student in the School of Computing at KAIST. I work with Juho Kim as a member of KIXLAB.

My research interest is using data-driven method, especially applying machine learning and NLP model to solve problems in education domain.

Research Experience

From Jan. 2018 to Dec. 2019, as a Research Assistant at the Electronics and Telecommunications Research Institute(ETRI), I worked on performing analysis of Spectral Efficiency for LTE with probabilistic modeling and Deep Neural Network. I also worked on research to predict future Resource Block Usage with stochastic modeling and Recurrent Neural Network. During the research, I was advised by Yunbae Kim.
