About
Hello! I am a final-year PhD Student at the Language & Knowledge Lab at KAIST, advised by Minjoon Seo. I am interested in building a robust semi-parametric model that aligns with external knowledge modules thereby capitalizing on the strengths of both the model’s parametric knowledge space and external nonparametric knowledge space, aiming to achieve the optimal performance. Previously, I graduated with M.S. at the Language & Knowledge Lab at KAIST, advised by Minjoon Seo, and B.S. from KAIST in computer science and electrical engineering (double major), where I was advised by Edward Choi and Hyun Wook Park.Publications
