Since January 2015, I've been a PhD student in the Department of Computer Science
at the University of British Columbia.
My supervisors are Jim Little and Holger Hoos. I do research in computer vision.

On human motion prediction using recurrent neural networks. In CVPR 2017 (29.84% acceptance rate)
We take a close look at deep recurrent approaches for human motion prediction, and propose a simple and scalable architecture that outperforms the state of the art.

Revisiting additive quantization. In ECCV 2016 (26.6% acceptance rate)
Additive quantization (AQ) is a promising vector compression approach for large-scale approximate nearest neighbour search. We introduce an optimization method for AQ that pushes it beyond the state of the art.

Efficient video-based retrieval of human motion with flexible alignment. In WACV 2016
We formalize the problem of video-based mocap retrieval. We also investigate different retrieval methods for this task.

Stacked quantizers for compositional vector compression. In arxiv (2014)
Some of my early attempts to improve multi-codebook quantization. This approach is equivalent to enhanced RVQ, and has been superceeded by our work on revisiting AQ. The code is very accessible though!

Complement to our work on Revisiting AQ. Details our GPU implementation.

A vector is mapped to one of many hash functions, which improves accuracy at increased query time.
I am/have served as a reviewer for CVIU, ICRA 16, CVPR 18, ECCV 18, IROS 18, NIPS 18.
On the fall of 2014 I started organizing CVRG, the Computer Vision Reading Group at UBC.
