Projects
clean-usnob Hybrid-Space Diffusion for Task and Motion Planning with Offline RL
Jisu Han, Yoonyoung Cho, and Haewon Jung (AI707: Advanced Topics in Deep Learning (Prof. Kimin Lee) Class project)

TL;DR To resolve the downward refinement issues from bi-level planning in Task and Motion planning (TAMP), we adopt hybrid-space diffusion model.
[Project]
clean-usnob Clarifying the task: Identifying task from human videos as a representation
Jisu Han and Doohyun Lee (AI611: Machine Learning for Robotics (Prof. Joseph Lim) Class project)

TL;DR To learn a generalized reward function that can be utilized on reinforcement learning, we devise a representation that can effectively disentangle environment information and task information.
[Project]
clean-usnob Compositional Meta Reinforcement Learning
Yoonyoung Cho and Jisu Han (AI614: Advanced deep learning (Prof. Sungju Hwang) Class project)

TL;DR We inject compositional reasoning for robots to quickly learn novel tasks by leveraging reusable elements from previous experiments.
