I am currently a PhD student at College of Computing, Georgia Tech. Prior to that, I obtained my Masters degree in 2010. I work with Prof. Guy Lebanon. I received my Bachelors degree from Madras Institute of Technology in 2008. As an undergrad, I worked on wireless communications and information theory. Yes, I select text while reading :)


Research

I am interested in several aspects of statistical machine learning. Specific research interests include:
  • Estimation procedures for complex, high dimensional data.
  • Labeling complexity reduction methods (for classification, regression and structured prediction) and its theoretical analysis.
More importantly, I am interested in examining if the blessings of high dimensionality could be used for reducing label complexity.
