Reinforcement Learning Algorithms with Python

Summary

In this chapter, we addressed the exploration-exploitation dilemma. This problem has already been tackled in previous chapters, but only in a light way, by employing simple strategies. In this chapter, we studied this dilemma in more depth, starting from the notorious multi-armed bandit problem. We saw how more sophisticated counter-based algorithms, such as UCB, can actually reach optimal performance, and with the expected logarithmic regret.

We then used exploration algorithms for AS. AS is an interesting application of exploratory algorithms, because the meta-algorithm has to choose the algorithm that best performs the task at hand. AS also has an outlet in reinforcement learning. For example, AS can be used to pick the best policy ...
