- Abstract:

Reinforcement Learning (RL) is an important research area in the field of machine learning and artificial intelligence and has received increasing attentions in recent years. The goal in RL is to maximize long-term total reward by interacting with the environment. Traditional RL algorithms are limited due to the so-called curse of dimensionality, and their learning abilities degrade drastically with increases in the dimensionality of the state space. Hierarchical reinforcement learning (HRL) decomposes the RL problem into sub-problems and solves each of them to improve learning ability. HRL offers a potential way to solve large-scale RL, which has received insufficient attention to date. In this paper, we introduce and review several main HRL methods.
