Friday 10th October 2003 - Cross Entropy & EM for RL
Mark (and Mike if he's in the country) will cover the Cross-entropy method for optimization and EM for Reinforcement Learning. These are apparently related.
Please look at least one of the topics. The CE stuff is longer.
See the CE method website and especially its tutorial.
Using EM for Reinforcement Learning - Peter Dayan and Geoffrey E Hinton.
