Hi, I’m Jinsung

I am currently a Ph.D candidate at POSTECH CVLab (Advisor: Prof. Suha Kwak), where I am having fun doing research!

I am interested in designing a compressive neural networks that extract the most informative features within a fixed space of limited complexity. I believe that state-space models (SSMs) offer valuable properties for achieving this goal, and I am actively exploring their application in my work. Previously, I worked on video understanding tasks, such as human action recognition and long-term context modeling.
