Yizhou (Philip) Huang

I am a first-year MSc student in Computer Science at the University of Toronto and a member of the Robot Vision and Learning (RVL) lab. I'm co-supervised by Prof. Florian Shkurti and Prof. Tim Barfoot. My research is generously funded by the CGS-M Scholarships and the Vector Scholarship in AI.

I have also been fortunate to work under many fantastic researchers in robotics. Previously, I collabrated with Prof. Fabio Ramos from Nvidia and on task and motion planning. In undergrad, I was involved in the student design team aUToronto, where we competed and won the SAE Autodrive Challenge. I also spent one amazing summer in Israel with Prof. Amir Degani and the summer before that with Prof. Angela Schoellig.

Research

The goal of my research is to improve robot's ability to model uncertain environments and make plans for complex and long-horizon tasks. Towards this end, I am currently working on planning algorithms for autonomous surface vessel (ASV) in Canadian lakes. Before that, I have also also explored continual learning in learning dynamics model for control.

Learning Heuristics for Minimum Latency Problem with RL and GNN
Course Project
University of Toronto, MIE 1666 Machine Learning for Mathematical Optimization
Final Report/ Presentation/ Code

RL can be applied to the Minimum Latency Problem by using a graph attention network to encode stochastic policy for constructively building partial paths, yielding solutions which are comparable to state-of-the-art, hand-engineered methods.

Linear-Time Dynamics using Lagrange Multipliers
Course Project
University of Toronto, CSC 2549 Physics-based Animation
Final Report/ Video/ Code

Re-implemented the SIGGRAPH 96 paper from David Baraff that introduced a linear-time sparse solver with Lagrangian multiplers in MATLAB. Verified that the time complexity of our re-implemented sparse solver is linear with serial chains and trees.

Evaluating Different Methods of Text Style Transfer
