Guanzhi Wang

I am a first-year Ph.D. student at Caltech, advised by Prof. Anima Anandkumar.

I obtained my M.S. degree from Stanford University, where I have been fortunate to work with Prof. Fei-Fei Li, Prof. Yuke Zhu, Dr. Jim Fan and Shyamal Buch. I got my B.S. degree from the Hong Kong University of Science and Technology, where I have been lucky to work with Prof. Chi-Keung Tang and Prof. Yu-Wing Tai. Previously, I was a research intern at Tencent YouTu.

My research interests lie in the area of robotics and computer vision. I am passionate about building intelligent agents to acquire rich and robust visual representations proactively and solve real-world robotic tasks efficiently.

MineDojo: Building Open-Ended Embodied Agents with Internet-Scale Knowledge
Linxi Fan, Guanzhi Wang*, Yunfan Jiang*, Ajay Mandlekar, Yuncong Yang, Haoyi Zhu, Andrew Tang, Yuke Zhu, Animashree Anandkumar
[paper]   [project page]   [code]  

We introduce MineDojo, a new framework based on the popular Minecraft game for building generally capable, open-ended embodied agents.

SECANT: Self-Expert Cloning for Zero-Shot Generalization of Visual Policies
Linxi Fan, Guanzhi Wang, De-An Huang, Zhiding Yu, Li Fei-Fei, Yuke Zhu, Animashree Anandkumar
International Conference on Machine Learning (ICML), 2021
[paper]   [project page]   [code]  

We proposed SECANT, a novel self-expert cloning technique that leverages image augmentation in two stages to decouple robust representation learning from policy optimization.

iGibson 1.0: a Simulation Environment for Interactive Tasks in Large Realistic Scenes
Bokui Shen*, Fei Xia*, Chengshu Li*, Roberto Martín-Martín*, Linxi Fan, Guanzhi Wang, Claudia D’Arpino, Shyamal Buch, Sanjana Srivastava, Lyne P. Tchapmi, Micael E. Tchapmi, Kent Vainio, Josiah Wong, Li Fei-Fei, Silvio Savarese
International Conference on Intelligent Robots and Systems (IROS), 2021
[paper]   [project page]   [code]  

We presented iGibson, a novel simulation environment for developing interactive robotic agents in large-scale realistic scenes.

Deep Video Matting via Spatio-Temporal Alignment and Aggregation
Yanan Sun, Guanzhi Wang*, Qiao Gu*, Chi-Keung Tang, Yu-Wing Tai
Conference on Computer Vision and Pattern Recognition (CVPR), 2021
[paper]   [code]   [dataset]

We proposed a deep learning-based video matting framework which employs a novel and effective spatio-temporal feature aggregation module.

RubiksNet: Learnable 3D-Shift for Efficient Video Action Recognition
Linxi Fan*, Shyamal Buch*, Guanzhi Wang, Ryan Cao, Yuke Zhu, Juan Carlos Niebles, Li Fei-Fei
European Conference on Computer Vision (ECCV), 2020
[paper]   [project page]   [video]   [supplementary]   [code]  

We proposed RubiksNet, a new efficient architecture for video action recognition based on a proposed learnable 3D spatiotemporal shift operation (RubiksShift).

LADN: Local Adversarial Disentangling Network for Facial Makeup and De-Makeup
Qiao Gu*, Guanzhi Wang*, Mang Tik Chiu, Yu-Wing Tai, Chi-Keung Tang
International Conference on Computer Vision (ICCV), 2019
[paper]   [project page]   [code]   [dataset]

We proposed a local adversarial disentangling network for facial makeup and de-makeup, using multiple and overlapping local discriminators in a content-style disentangling network.
