Summary

We present an approximate policy iteration algorithmthat uses rollouts to estimate the value of eachaction under a given policy in a subset of states anda classifier to generalize and learn the improvedpolicy over the entire state space. Using a multiclasssupport vector machine as the classifier, weobtained successful results on the inverted pendulumand the bicycle balancing and riding domains.
