How much do you need to know about the future to take the right decisions?

In this talk, I will briefly review two influential recent works in Bayesian Reinforcement Learning, and then move on to my own work in progress, on an attempt to find a good Gaussian approximation to the Bellman posterior over values. Unfortunately, the “right” Gaussian fit turns out to be very difficult to track, but a simplistic approximation gives surprisingly good results. Preliminary experiments suggest that this approach compares favorably to contemporary Reinforcement Learning algorithms.

This talk is part of the Inference Group series.
