I'm a PhD student in the Computer Science Department. My research
interests lie in machine learning and planning. In particular, I'm
interested in applying fast online algorithms and structured models to
real-world problems. My thesis work is on multi-agent planning under
uncertainty with shared resources. Ultimately, it'd be nice to help save
the world with machine learning / game theory (e.g. solving
environmental problems, designing public policy, eliminating
inefficiency wherever possible).
My advisor is Geoff
Gordon. Previously I worked with
Tom Mitchell on
reading the web
by extracting facts from web text using co-training-style
semi-supervised learning algorithms.
I've been also working on a couple of cool art projects that use machine learning.

- Read the Web. Our ultimate goal is to build an information extraction
system that learns to extract and accumulate facts from text, and uses
those facts to learn to extract better. The basis of the system builds
upon ideas from bootstrap information extraction and co-training to
classify entities and relations for predefined classes, starting with a
handful of examples each. Preliminary results and a starting system
description can be found in our position paper:

- Hot? Or Not: learning to evaluate facial attractiveness based on images
and ratings. We employed eigenfaces and fisherfaces with SVMs to classify
the attractiveness of rectified facial images given the average of many
ratings from a popular website. Unfortunately, the method did not yield
great results, most likely due to the weak feature representation.
