Meta AI for RL

Menlo Park, CA 94025

United States

I’m a AI research scientist at Meta AI for RL and an affiliate assistant professor in the department of Electrical Engineering, University of Washington. I was a principal researcher at Microsoft Research, Redmond. Before joining Microsoft, I obtained my PhD degree in Applied and Computational Mathematics from Caltech in 2017. My research interests are mainly in the areas of deep learning, computer vision, multimodal intelligence, and theoretical foundations for deep learning.

Oct 22, 2022 Our ECCV2022 workshop ‚ÄúComputer Vision in the Wild‚ÄĚ https://computer-vision-in-the-wild.github.io/eccv-2022/ is taking place 9:00am-6:00pm Israeli Time, 11:00pm (October 22)-8:00am Pacific Time, 2:00pm-11:00pm Beijing Time. I will be chairing the monirng section. Welcome to attend the workshop!

We are also organizing an ECCV2022 workshop https://computer-vision-in-the-wild.github.io/eccv-2022/ Last call for papers and challenge participation in solving problems on open-set recognition and task-level visual transfer.
Jun 8, 2022 2 pieces of updates on our recent vision-and-language efforts: (i) Our CVPR 2022 tutorial will happen on 06/19/2022; (ii) Our ECCV2022 workshop of Computer Vision in the Wild will happen at ECCV2022 in October 2022. There will be two challenges associated with this workshop: Image Classification in the Wild and Object Detection in the Wild. The challange setup and baselines can be found in our ELEVATER benchmark paper. Stay tuned for more details.
May 3, 2022 I’m starting a new position as Research Scientist at Meta AI for VR. I will continue my long-term pursuit of CV and Multi-modal intelligence at my new position. Looking forward to work with colleagues and the entire community, to build intelligent and trust-able technologies for the metaverse, and to push the research frontier of deep learning, CV and multi-modal.
Mar 11, 2022 Gave a talk at Applied and Computational Mathematics Seminar at University of Wisconsin at Madison. The talk is about my ICLM 2021 work ‚ÄúMultiscale Invertible Generative Networks for High-Dimensional Bayesian Inference‚ÄĚ. The talk slides can be found at here.
