(edit 2013: I've finished the Ph.D.) a Ph.D. student in the
Machine Learning Group
Department of Computer Science
University of Toronto
, where I also received my M.Sc.
in January of 2008
I graduated from
in June of 2006 with a BS in
I was on leave, working as a machine learning consultant, from August 2008 - August 2009.
My advisor is Richard Zemel
I also work frequently with Ryan Adams
and Brendan Frey
In January 2013, I will be joining Microsoft Research Cambridge
as a Postdoctoral Researcher
and will be a Research Fellow at Darwin College
at the University of Cambridge
Broadly, I'm interested in applying machine learning to problems where examples come in the form of complex, structured
objects. How can we best learn by example when our examples are things like image segmentations, bipartite
matchings, paths in a graph, or (perhaps someday) computer programs?
What computational tools and models do we need to be able to tractably work in these settings? How can
we better model these settings without sacrificing computational efficiency?
Some specific interests:
- Inference in discrete graphical models: message passing, network flows, and linear programming;
message scheduling and dynamic inference.
- Structured output learning; complex loss functions on structured output spaces.
- High(er) order models.
- Computer vision, specifically with respect to image-labeling models.
Some selected past projects and positions:
- Research Intern at Microsoft Research Cambridge (UK) (2010)
Supervisor: Tom Minka.
