Bio

2005-2009 Undergraduate degree: CS, Physics and Math at University of Toronto.
2009-2011 Master's degree: CS at University of British Columbia. I worked with Michiel van de Panne on problems of Motor Control in physically simulated articulated figures.
2011 Google Research: I was a summer intern at Google Research in Mountain View. I worked on a highly-classified project involving large-scale Machine Learning and Computer Vision :)


My main research interests are now in Machine Learning, and my preferred application domain is Vision.

I am also very passionate about:

  • Robotics
  • Neuroscience, Neural network models, Intelligence
  • Evolution, Abiogenesis, Genetics
  • Computability, Complexity, Formal systems, Models of computation
  • Superorganisms, Swarms, Self-organisation
  • Chaos, Fractals, Irreducible dynamical systems

I maintain a mostly academic blog for fun. I wish all researchers had one.

Teaching Assistant

Stanford Fall 2011, #mlclass: Machine Learning Online Class (assignments)

Lectures
 I make educational videos on YouTube for fun:
Solving the Rubik's cube :p (Beginner to Expert) (I'm qualified because I solve cubes in ~17seconds on average)
Game Programming in Python Tutorials
Fractal Mathematics Tutorials
Machine Learning Tutorials (work in progress ;p)

Coding
mini-projects
 Biased sampling from distribution of my projects:

Library for training binary Restricted Boltzmann Machines (MATLAB)
Evolutionary Artificial Life Simulator of Predator-Prey dynamics (C++)
Rubik's cube color extractor (Python)
iPhone app (ObjC). Made over $10,000 on this so far :) Currently working on other more elaborate apps.
Sketcher [video] (Python) simulates a person drawing an image.
Tetris AI [video] (Python) is a Tetris AI player that can hold its own for few hours.
4 seasons animation [video] (Python) simulates a tree through 4 seasons and looks pretty. I've sold rights to this animation for $200 a year ago.

- Many more crappy projects I worked on long time ago. [videos]
- Github account, not as full as I'd like it to be.
Personal

- I maintain a separate personal website where you can find my projects
- Advice for doing well in undergrad classes
- Little comic-like things I make for fun sometimes
