The character generation example is useful to show that RNN's are capable of learning temporal dependencies over varying ranges of time. Temporal Difference Learning In the previous chapter, we learned about the interesting Monte Carlo method, which is used for solving the Markov Decision Process ( MDP ) when the model dynamics of the environment are not known in advance, unlike dynamic programming. The latter requirement is important because each vertex in the graph object will also be a container, holding a subpopulation of agents which are. The modern machine learning approaches to RL are mainly based on TD-Learning, which deals with rewards signals and a value function (we'll see more in detail what these are in the following paragraphs). The straightforward (but wrong) extension of the RW rule to time is:. Structural learning works in the same way to standard Bayesian networks, except that both temporal links and non-temporal links are discovered.
