强化学习是指一个''智能体（agent）''应该如何在''环境''中采取''行动''，从而最大限度地获得长期''报酬''的概念。强化学习算法试图找到一种''策略''，将世界''状态''映射到智能体在这些状态中应该采取的行动。强化学习不同于[https://en.wikipedia.org/wiki/Supervised_learning 监督学习]问题，因为不会提供正确的输入/输出对，也没有明确地修正次优行为。
Reinforcement learning is an area of machine learning concerned with how [[software agent]]s ought to take [[Action selection|actions]] in an environment so as to maximize some notion of cumulative reward. Due to its generality, the field is studied in many other disciplines, such as [[game theory]], [[control theory]], [[operations research]], [[information theory]], [[simulation-based optimization]], [[multi-agent system]]s, [[swarm intelligence]], [[statistics]] and [[genetic algorithm]]s. In machine learning, the environment is typically represented as a [[Markov Decision Process]] (MDP). Many reinforcement learning algorithms use [[dynamic programming]] techniques.<ref>{{Cite book|title=Reinforcement learning and markov decision processes|author1=van Otterlo, M.|author2=Wiering, M.|journal=Reinforcement Learning |volume=12|pages=3–42 |year=2012 |doi=10.1007/978-3-642-27645-3_1|series=Adaptation, Learning, and Optimization|isbn=978-3-642-27644-6}}</ref> Reinforcement learning algorithms do not assume knowledge of an exact mathematical model of the MDP, and are used when exact models are infeasible.

强化学习是机器学习的一个分支，它研究软件组件应该如何在某个环境中进行行动决策，以便最大化某种累积收益的概念。由于其存在的普遍性，该领域的研究在许多其他学科，如'''博弈论 Game Theory'''，'''控制理论 Control Theory'''，'''运筹学 Operations Research'''，'''信息论 Information Theory'''，'''基于仿真的优化 Simulation-based Optimization'''，'''多主体系统 Multi-agent System'''，'''群体智能 Swarm Intelligence'''，'''统计学 Statistics'''和'''遗传算法 Genetic Algorithm'''。在机器学习中，环境通常被表示为'''马可夫决策过程 Markov Decision Process ，MDP'''。许多强化学习算法使用动态编程技术。强化学习算法不需要知道 MDP 的精确数学模型，而是在精确模型不可行的情况下使用。强化学习算法常用于车辆自动驾驶问题或人机游戏场景。
