Yunshuang Li 李雲霜

I am an incoming Ph.D. student in Computer Science at University of Southern California, where I will work with Prof. Daniel Seita and Prof. Gaurav Sukhatme. I am interested in robot learning for general-purpose robot manipulation.

I will receieve a M.S. degree in Robotics at GRASP Lab, University of Pennsyvania in May 2024. I was a member of Perception, Action, & Learnin (PAL) Research Group, advised by Prof. Dinesh Jayaraman. Previoulsy, I worked with Prof. Qi Dou at Chinese University of Hong Kong (CUHK) for an internship. I received my Honorable B.S. degree in Automation from Chu Kochen Honors College, Zhejiang University in 2022.

Research

My research interests lie in robot learning for general-purpose robot manipulation. During my PhD study, I would like to focus on learning for robot manipulation, exploring topics such as representation learning and policy learning. My ultimate goal is to enable robots to manipulate and learn to manipulate like humans.

We present Universal Visual Decomposer, an *off-the-shelf* task decomposition method that effectively produces semantically meaning subgoals across both simulated and real-robot environments for long-horizon visual manipulation tasks, without any task-specific knowledge or training. UVD discovered subgoals enable effective reward shaping for solving challenging multi-stage tasks using RL, and policies trained with IL exhibit significantly superior compositional generalization at test time.

We propose a challenging vision-based extrinsic contact localization task: with only a single RGB-D camera view of a robot workspace, identify when and where an object held by the robot contacts the rest of the environment. Our final approach im2contact demonstrates the promise of versatile general-purpose contact perception from vision alone, performing well for localizing various contact types (point, line, or planar; sticking, sliding, or rolling; single or multiple), and even under occlusions in its camera view.

This is the report paper on Workflow Recognition Challenge in MICCAI 2021. I lead the MedAIR team and rank the first over all the 5 rank method in one sub-challenge on multi-modal (videos and kinematics) workflow recognition of robotic surgery videos.
