Bayesian Policy Search with Policy Priors

These are some supporting videos for the paper
Bayesian Policy Search with Policy Priors
by David Wingate, Noah D. Goodman, Daniel M. Roy, Leslie P. Kaelbling and Joshua B. Tenenbaum,
published in International Joint Conference on Artificial Intelligence (IJCAI), 2011.

The videos illustrate the differences that structured prior knowledge with an
appropriate policy search algorithm can make in complex domains with reusable
chunks of policy:
