Yongjun Cho
A Senior Research Scientist at WoRV (World model for Robotics and Vehicle control) team of Maum AI, I have 3 years and 7 months of experience in the AI startup industry. I completed a master's program at the School of Electrical Engineering of Korea Advanced Institute of Science and Technology (KAIST) advised by Dong Eui Chang, specializing in Artificial Intelligence and Reinforcement Learning.
My research focuses on achieving generalization performance in robotics and AI by leveraging imitation learning, reinforcement learning, and vision-language models. I believe that large-scale physical interaction data is crucial to solving this challenge, ultimately aiming to make AI a companion to humans through an 'open-source Physical AI ecosystem' that learns physical laws and gathers extensive object interaction data to overcome both generalization and hardware limitations.
Research Interest: Robotics, Autonomous Navigation, Imitation Learning, Reinforcement Learning, Vision-Language-Action Models, Generalization in AI
