I’m a fourth year graduate student at Lab for Information and Decision Systems (LIDS) at MIT advised by Prof. Guy Bresler. I work on various problems in theoretical machine learning([1]), applied probability and statistics. My current work focuses on representation power of deep neural networks, random graphs with latent geometric structure and stochastic optimization algorithms. Previously I was an undergraduate student at IIT Madras.
