• Reinforcement learning has attracted the attention of researchers in AI and related elds for quite some time. Many reinforcement learning algorithms exist and for some of them convergence rates are known. However, Kearns and Singh’s E3 algorithm (Kearns and Singh, 1998) was the rst provably near-optimal polynomial time algorithm for learning •Hierarchical Reinforcement Learning. Action hierarchy, hierarchical RL, semi-MDP. Hierarchical reinforcement learning. Three approaches to HRL • Options: Sutton (temporal + state abstraction) MAXQ-0 learning algorithm • Given action hierarchy. • Each subtask has zero pseudo terminal reward.•actions. This relationship naturally leads us to reinforcement learning. Based on the learning goals, most reinforcement learning algorithms can be bucketed into critic-based and actor-based methods. Critic-based methods, such as Q-learning or TD-learning, aim to learn to learn an optimal value-function for a particular problem.
