Welcome
I am Ravi Sastry Ganti Mahapatruni (the first two words constitute my first name and the last two my last name) a fourth year graduate student in the Computer Sciences department at Georgia Institute of Technology . My interests are in statistical machine learning, statistical learning theory and nonparametric statistics. I am advised by Alex Gray. I have also had the good fortune of working with Adam Kalai. I have mostly worked on problems in nonparametric statistics in general and kernel density estimation in specific, where the aim is to learn estimators that can adapt to the heterogeneous smoothness of the underlying density function. Of late I have been excited about using results from statistical learning theory in algorithm design, and I think active learning is one such area where there is immense scope for desigining practical and efficient algorithms driven by insights from statistical learning theory.

I graduated with a Bachelors degree in computer science and engineering from IIT Kharagpur 2007. As an undergraduate I worked on problems in NLP for my bachelors thesis. I was fortunate enough to work with Monojit Choudhury from whom I learnt some NLP and some machine learning.

An up-to-date CV can be found here.

In conjunction with Krishna we are organizing the machine learning reading group every Thursday 3:00-4:00 PM. If you are interested in giving a talk do contact one of us.
