Tales of Bayesian Regression

In this talk, I will discuss few case studies for unusually accurate predictions with unstructured data. We develop and utilize the method of Bayesian Regression for what we call "Latent Source Model". The basic insight is quite simple. There are only few distinct ways in which phenomenon of interest occurs. Be it topics trending on Twitter, price variations in Bitcoin or choices consumers make in going to restaurants, shopping clothes or watching movies. The method is embarrassingly parallel and scalable while being highly accurate.

His primary research interest is in developing large-scale machine learning algorithms for massive unstructured data. He has made contributions to development of “gossip” protocols and “message-passing” algorithms which have been pillar of modern distributed data processing systems.

He has received 2010 Erlang Prize from INFORMS. He is a distinguished young alumni of his alma mater IIT Bombay.
