摘要:

逆向约束强化学习(ICRL)是基于专家智能体的演示数据,推断其遵循的隐式约束的任务。作为一个新兴研究课题,ICRL近年来受到广泛关注。本文对ICRL的最新进展进行了分类综述。它为机器学习研究人员和从业者,以及希望理解ICRL定义、进展和重要挑战的初学者提供了全面参考。我们首先正式定义了问题,并概述了促进各种场景下约束推断的算法框架。这些场景包括确定性或随机环境、演示数据有限的环境以及多智能体环境。对于每种情况,我们阐明了关键挑战,并介绍了一系列解决这些问题的基本方法。本综述涵盖了用于评估ICRL智能体的离散、虚拟和现实环境。我们还深入探讨了ICRL最相关的应用,如自动驾驶、机器人控制和体育分析。为了促进持续研究,我们在最后讨论了ICRL中关键且未解决的问题,以有效搭建理论理解与实际工业应用之间的桥梁。本综述引用的论文可在https://github.com/Jasonxu1225/Awesome-Constraint-Inference-in-RL找到。

英文摘要:

Inverse Constrained Reinforcement Learning (ICRL) is the task of inferring the implicit constraints that expert agents adhere to, based on their demonstration data. As an emerging research topic, ICRL has received considerable attention in recent years. This article presents a categorical survey of the latest advances in ICRL. It serves as a comprehensive reference for machine learning researchers and practitioners, as well as starters seeking to comprehend the definitions, advancements, and important challenges in ICRL. We begin by formally defining the problem and outlining the algorithmic framework that facilitates constraint inference across various scenarios. These include deterministic or stochastic environments, environments with limited demonstrations, and multiple agents. For each context, we illustrate the critical challenges and introduce a series of fundamental methods to tackle these issues. This survey encompasses discrete, virtual, and realistic environments for evaluating ICRL agents. We also delve into the most pertinent applications of ICRL, such as autonomous driving, robot control, and sports analytics. To stimulate continuing research, we conclude the survey with a discussion of key unresolved questions in ICRL that can effectively foster a bridge between theoretical understanding and practical industrial applications.
