Daehyeon Choi Master. Student @ KAIST, C.S
Previously, I recevied a Bachelor of Science (B.S.) degree at POSTECH, 2025. I was an Intern in GenGenAI and Meissa Planet. And, I was an undergraduate intern in SNU, POSTECH, and KAIST. Thanks to them, I was able to drastically revolutionize my skills.
Currently, I am interested in Large Vision-Language Model, especially Visual Grounding leveraging pre-trained large-scale model's prior.
