Minyoung Hwang

I'm an incoming graduate student at MIT, advised by Andreea Bobu. Previously, I worked at CMU, advised by Yonatan Bisk, and Allen Institute for AI (AI2). I received my M.S. and B.S. in ECE at Seoul National University (SNU).

Research Keywords: robotics, human-robot interaction, reinforcement learning, computer vision


Previously, I was a research intern at CMU, advised by Yonatan Bisk. Before that, I was a research intern at the PRIOR team of the Allen Institute for AI (AI2), supervised by Kiana Ehsani and closely worked with Ani Kembhavi and Luca Weihs. I received my M.S. in the Robot Learning Laboratory (RLLAB, advised by Songhwai Oh), Department of Electrical and Computer Engineering at Seoul National University (SNU), Korea. I was co-advised by Yoonseon Oh and Kyungjae Lee during my M.S. program. I received a B.S. degree (with highest honors) in Electrical and Computer Engineering from SNU in 2021. When I was an undergraduate, I fell into robotics and developed an omnidirectional motion-controlled robot cleaner with a wonderful team in SNU. I also participated the Silicon Valley Innovation - Startup Training Program in San Jose State University and was mentored by Koohyoung Lee (CTO of NeuroSky). Before my B.S., I majored Mathematics in Daejeon Science High School for the Gifted.

Skills: I received numerous awards for talent in Mathematics. I was honored to be fully supported by the Presidential Science Scholarship in Mathematics during my undergraduate degree. For details, go to Honors and Awards. I TAed 4+ Math/ECE lectures and I love to share my knowledge and insights with others.

I'm interested in robotics, human-robot interaction, computer vision, and reinforcement learning. Much of my research is about applying mathematical concepts/theories to robot learning. Representative papers are highlighted.

Promptable Behaviors: Personalizing Multi-Objective Rewards from Human Preferences
Minyoung Hwang, Luca Weihs, Chanwoo Park, Kimin Lee, Ani Kembhavi, Kiana Ehsani
CVPR (Computer Vision and Pattern Recognition), 2024
project page | code | paper

We propose a novel framework that facilitates efficient personalization of robotic agents to diverse human preferences in complex environments.

Sequential Preference Ranking for Efficient Reinforcement Learning from Human Feedback
Minyoung Hwang, Gunmin Lee, Hogun Kee, Chan Woo Kim, Kyungjae Lee, Songhwai Oh
NeurIPS (Neural Information Processing Systems), 2023
project page | paper

We propose a novel RLHF framework called SeqRank, that uses sequential preference ranking to enhance the feedback efficiency.

Meta-Explore: Exploratory Hierarchical Vision-and-Language Navigation Using Scene Object Spectrum Grounding
Minyoung Hwang, Jaeyeon Jeong, Minsoo Kim, Yoonseon Oh, Songhwai Oh
CVPR (Computer Vision and Pattern Recognition), 2023
project page | video | paper | poster

We propose and end-to-end learnable hierarchical navigation policy for vision-and-language navigation (VLN) that finds an unvisited and near-optimal local goal by recognizing semantically meaningful clues.

Improving Image-Goal Navigation with Visual Language Grounding via Image Captioning
Minyoung Hwang, Songhwai Oh
CICS (Conference on Information and Control Systems), 2022

We propose a visual navigation method that the agent augments language observations and use the multi-modal observations for hierarchical exploration.

Geometric Understanding of Reward Function in Multi-Agent Visual Exploration
Minyoung Hwang, Obin Kwon, Songhwai Oh
ICCAS (International Conference on Control, Automation and Systems), 2021
video | paper

We present a new reward shaping method for multi-agent visual exploration with geometric understanding of the environment.

Video Inference for Human Motion with Texture Generation
Minyoung Hwang, Songhwai Oh
Bachelor's Thesis, Electrical and Computer Engineering Department, Seoul National University, Korea, Oct 2020
video | paper | poster

We propose a novel method to reconstruct 3D multi-view video with texture generation from a 2D human motion video.


I hosted and participated in some challenges.

RC Car Racing Challenge
Robot Learning Laboratory, SNU
Head TA
TA demo | project page | videos and photos

We hosted RC car racing challenges in 2022 Spring & 2021 Fall ECE 430.457 'Introduction to Intelligent Systems'.
