个人简介
My research group is engaged in fundamental research in the following areas:
Statistical learning theory: We are developing theory and algorithms for predictions problems (e.g., learning to rank and multilabel learning) with complex label spaces and where the available human supervision is often weak.
Sequential prediction in a game theoretic framework: We are trying to understand the power and limitations of sequential prediction algorithms when no probabilistic assumptions are placed on the data generating mechanism.
High dimensional and network data analysis: We are developing scalable algorithms with provable performance guarantees for learning from high dimensional and network data.
Optimization algorithms: We are creating incremental, distributed and parallel algorithms for machine learning problems arising in today's data rich world.
Reinforcement learning: We are synthesizing and further developing concepts and techniques from artificial intelligence, control theory and operations research for pushing forward the frontier in sequential decision making with a focus on delivering personalized health interventions via mobile devices.
I like to work in multi-disciplinary teams and am always interested in discussing challenging machine learning problems in any scientific field including behavioral sciences, chemistry, learning sciences, life sciences, and network science.
My almae matres are IIT Kanpur (B.Tech., 2002) and UC Berkeley (M.A., 2005 and Ph.D., 2007. Advisor: Peter Bartlett). I was a research assistant professor at TTIC from 2008 to 2010. From 2010 to 2012, I was a post-doctoral fellow at UT Austin where I worked with Inderjit Dhillon and Pradeep Ravikumar.
Activities at U-M I'm involved with:
Big Data Summer Institute
Learning Analytics at Michigan
Michigan Institute for Data Science (MIDAS)
Pushing Mobile Interventions Forward (a seminar series I coordinate; also see this short video from a talk I gave at NYAS)
Statistical Machine Learning Reading Group
Statistical Reinforcement Learning at Michigan
