Hongsuk Benjamin Choi

Researcher

I am a Machine Learning / Computer Vision Researcher at Samsung AI center, New York. I received a Master’s degree at Seoul National University (SNU) computer vision lab after converting my PhD program. I was advised by Prof. Kyoung Mu Lee, Editor in Chief (EIC), IEEE Trans. on PAMI (Pattern Analysis and Machine Intelligence). Please refer to my CV for more information. Email: redstonepo@gmail.com

Introduction

I am interested in a broad range of machine learning and computer vision topics. I have in-depth experience in 3D reconstruction and neural image generation.

• Over 5 years of software engineering experience in both small and large companies, performing frontend, backend, and AI research
• In-depth experience in large language model, generative AI, and 3D reconstruction models. Maintain opensource projects
• First authored 7 papers out of 11 total papers (ex. CVPR, ICLR, ICRA) and filed 3 patents, most completed during my 2 years in a Master’s program
• Strong expertise in Python and Pytorch. Familiar with CUDA
