I like to explore and create. I spend most of my time studying how to realize artificial intelligence in physical and virtual environments. I graduated from the University of Chicago with B.S. in mathematics and B.A. in physics. I am currently a PhD candidate at TTI-Chicago focusing on reinforcement learning (sequential decision making in an unknown environment). Professor Matthew Walter is my advisor.
Research interests
Foundation of reinforcement learning
Incorporating domain knowledge in reinforcement learning
Incorporating glyphs in Chinese natural language processing
Demos
Focus, simulating focus+depth visual effect with CSS 3D transform and CSS filter. (This demo requires webkit filter support, so it only works in the latest desktop Chrome browser)
Wikipedia Plus, a Chrome extension that enhances Wikipedia's user experience
TwiThinks, a Twitter data analytics project that studies and visualizes Twitter data. Our realtime #Ivoted (for Obama vs Romney) scoreboard received 20K+ hits on Election Day 2012.
Besides machine learning, I have interest in quantum theory, mathematical logic, philosophy, visualization, and emerging technologies and more. I often share my thoughts about them on my blog Substance.
