I am a principal scientist in the Cloud and Information Services Lab (CISL, pronounced as sizzle), an applied science group in Microsoft with Raghu Ramakrishnan as the head. I am located in Mountain View, CA. From Jan 2004-Apr 2012 I was with the Machine Learning Group of Yahoo! Research, in Santa Clara, CA. My recent research has mainly focused on the design of distributed training algorithms for developing various types of linear and nonlinear models on Big Data. Publications 2015 An efficient distributed learning algorithm based on effective local functional approximations. With Dhruv Mahajan, Nikunj Agrawal, S. Sundararajan and Leon Bottou, Submitted to JMLR, 2015. [abstract] A distributed block coordinate descent method for training l_1 regularized linear classifiers. With Dhruv Mahajan and S.
