July 28 2009 - NY Times!

Dinosaur Planet is in the New York Times!

July 26, 2009 - Netflix!!

Along with the rest of The Ensemble, I finished in first place on the Netflix Prize Leaderboard at the end of the competition! We may or may not have won the prize, but it is a major accomplishment and a strong argument for the benefits of open collaboration. See my Netflix page for more.

February 6, 2009 - Update

I finally updated the website with a slightly tweaked design, better fonts and up-to-date content.

about me

I am a second-year graduate student in the Computer and Information Science (CIS) Department at the University of Pennsylvania. I am co-advised by Ben Taskar and Michael Kearns, and I'm studying practical and theoretical machine learning. I hope to promote the integration of machine learning and neuroscience, to change the way we analyze and understand our minds.

Previously, I was a research specialist at the Princeton Computational Memory Lab. I graduated from Princeton University with a degree in Computer Science and a certificate in Neuroscience in 2007, advised by Dave Blei (CS) and Ken Norman (Psychology).

In addition, I am a member of Team Dinosaur Planet, Grand Prize Team, and The Ensemble, the greatest Netflix wrecking crew ever created. I'm also a founding software developer of MedForward Inc., and a developer of the MVPA Toolbox for Matlab.

I married my high school sweetheart Gillian Braden-Weiss (née Braden) in May of 2008.
