Daehyeon Choi Incoming M.S. Student @ KAIST, C.S

My Selfie
I am Daehyeon Choi, Undergraduate student in POSTECH.
Previously, I was an Intern in GenGenAI. And, I was an Undergraduate Intern in Seoul National University. Thanks to it, I was able to drastically revolutionize my skills.
Currently, I am interested in Generative Model, especially Diffusion Models. I will start my M.S. course in KAIST Visual & AI Group, 2025, Spring.
And I am dealing with some problems about generative model and its applications, such as text-to-image synthesis, Image Editing, and so on.
