Rohit Babbar

Hello, I work in the Empirical Inference group headed by Prof. Bernhard Schölkopf , at Max-Planck Institute for Intelligent Systems, Tübingen, Germany. 

Research interests : Machine Learning for large-scale problems, Extreme Classification, Deep Learning, and Optimization... 

Before this, I finished my PhD in October 2014 from LIG lab of University of Grenoble Alpes,  France, where I was advised by Prof. Eric Gaussier and Prof. Massih-Reza Amini under the Class-Y project funded by the French National Research Agency (ANR). 

Extreme Classification Repository  - Maintained by Manik Varma, consists of Datasets and (links to) code for most recent methods for extreme classification

We are organizing MPI-ETH Pre-doc Summer School on Learning Systems from July 3 to Friday July 7, 2017 in Zürich, Switzerland for Master's students. Please encourage your students to apply.
