Ranjan Sarkar
Indian Institute of Technology Kharagpur
I am a PhD research scholar in the Department of Artificial Intelligence at IIT Kharagpur. I am interested in how intelligent systems can make good decisions when they cannot fully observe or predict the world around them. Most of my work sits where Reinforcement Learning, Stochastic Estimation and Optimization meet.
