Hyunjin Kim

I am a MS student in Computer Science at UC San Diego, where I am advised by Prof. Xiaolong Wang.

Before that, I received my BS in Urban Planning and Engineering and Computer Science and Engineering from Yonsei University. During my undergraduate studies, I worked with Prof. Jaesik Park at Seoul National University, and was an exchange student at the University of Toronto, where I worked with Prof. Florian Shkurti.

My research interests encompasses 3D computer vision, machine learning, and robotics. My research goal is to build computational models that can perceive and understand objects and environments as well as humans do. My research focuses on developing efficient generalizable 3D/4D scene reconstruction methods and spatial 3D/4D scene reasoning methods for Embodied AI. I am also dedicated to Robotic Simulation and Multimodal Scene Reconstruction.

Can Separators Improve Chain-of-Thought Prompting?
Yoonjeong Park*, Hyunjin Kim*, Chanyeol Choi, Junseong Kim, Jy-yong Sohn
IEEE The International Conference on Foundation and Large Language Models (FLLM), 2024.
Paper / Code

We present CoT-SEP, which includes separators between exemplars in Chain-of-Thought Prompting. CoT-SEP enhances LLM's reasoning ability with the simplest setup.
