Zhanyi Sun

I am a first-year Ph.D. student at Stanford Univeristy rotating with Prof. Shuran Song in the Robotics and Embodied AI (REAL) Lab.

Prior to Stanford, I was a MS-Research student in the CMU Robotics Institute, advised by Prof. David Held and Prof. Zackory Erickson.

Prior to CMU, I earned my B.A. in Computer Science and B.S. in Electrical Engineering from Rice University. During my time at Rice, I did research in under Prof. Vaibhav Unhelkar, Prof. Lydia E. Kavraki, and Prof. Yingyan (Celine) Lin.

RL-VLM-F: Reinforcement Learning from Vision Language Foundation Model Feedback
Yufei Wang*, Zhanyi Sun*, Jesse Zhang, Xian Zhou, Erdem Bıyık, David Held, Zackory Erickson
International Conference on Machine Learning (ICML), 2024
Project Page | Paper

We introduce a new method a method that automatically generates reward functions for agents to learn new tasks, using only a text description of the task goal and the agent’s visual observations, by leveraging feedback from vision language foundation models (VLMs).

fcvp Force Constrained Visual Policy: Safe Robot-Assisted Dressing via Multi-Modal Sensing
Zhanyi Sun*, Yufei Wang*, David Held, Zackory Erickson
IEEE Robotics and Automation Letters (RA-L), 2024
Project Page | Paper

We introduce a new method that leverages both vision and force modalities for robot-assisted dressing. Our method combines the vision-based policy,trained in simulation, with the force dynamics model, learned in the real world to achieve better dressing performance and safety for the user.

One Policy to Dress Them All: Learning to Dress People with Diverse Poses and Garments

Robotics: Science and Systems (RSS), 2023
Project Page | Paper | Video | CMU Research Highlights

We develop, for the first time, a robot-assisted dressing system that is able to dress different garments on people with diverse body shapes and poses from partial point cloud observations, based on a single Reinforcement Learning policy.

vitcod ViTCoD: Vision transformer acceleration via dedicated algorithm and accelerator co-design
Haoran You, Zhanyi Sun, Huihong Shi, Zhongzhi Yu, Yang Zhao, Yongan Zhang, Chaojian Li, Baopu Li, Yingyan Lin
IEEE International Symposium on High-Performance Computer Architecture (HPCA), 2023
Paper | Code | Video

We propose a dedicated algorithm and accelerator co-design framework dubbed ViTCoD to accelerate ViTs. On the algorithm level, we prune and polarize the attention maps to have either denser or sparser patterns. On the hardware level, we develop an accelerator to coordinate the denser/sparser workloads for higeher hardware utilization.

supertickets SuperTickets: Drawing Task-Agnostic Lottery Tickets from Supernets via Jointly Architecture Searching and Parameter Pruning
Haoran You, Baopu Li, Zhanyi Sun, Xu Ouyang, Yingyan Lin
European Conference on Computer Vision (ECCV), 2022
Paper | Code | Video

We discover for the first time that both efficient DNNs and their lottery subnetworks can be identified from a supernet and propose a two-in-one training scheme with jointly architecture searching and parameter pruning to identify them.

Human-guided motion planning in partially observable environments
Carlos Quintero-Pena*, Constantinos Chamzas*, Zhanyi Sun, Vaibhav Unhelkar, Lydia E. Kavraki
International Conference on Robotics and Automation (ICRA), 2022
Project Page | Paper | Video | Futurity Research News Review

We propose a method that leverages human guidance for high DOF robot motion planning in partial observable environments. We project the robot’s continuous configuration space to a discrete task model and utilize inverse RL to learn motion-level guidance from human critiques.
