Rohit Babbar

Hello, I am an Assistant Professor at the department of Computer Science, Aalto University in Finland. I will be starting a new research group working on problems in Large-scale Machine Learning, Shallow and 
Deep Learning for Extreme Classification, and Optimization.  

I am looking for students interested in doing PhD or Master's thesis in the above or related areas such as Deep learning for NLP. Please do not hesitate to contact at

Before this, I was working in the Empirical Inference group headed by Prof. Bernhard Schölkopf , at Max-Planck Institute for Intelligent Systems, Tübingen, Germany. Finished my PhD in October 2014 from LIG lab of University of Grenoble Alpes, where I was advised by Prof. Eric Gaussier and Prof. Massih-Reza Amini.

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