摘要:

本文综述了社会机器人中的强化学习方法。强化学习是一个决策问题的框架,其中智能体通过试错与环境交互,以发现最佳行为。由于交互是强化学习和社交机器人的关键组成部分,因此它可以成为与物理体现的社交机器人进行真实世界交互的非常合适的方法。本文的范围特别集中在包括社交物理机器人和现实世界中的人机交互与用户的研究。我们对社会机器人中的强化学习方法进行了深入的分析。除了调查,我们分类现有的强化学习方法的基础上使用的方法和奖励机制的设计。此外,由于通信能力是社交机器人的一个突出特点,我们讨论和分组的基础上用于奖励制定的通信介质的论文。考虑到设计奖励函数的重要性,我们还根据奖励的性质对论文进行了分类。这种分类包括三个主要主题:交互式强化学习,内在动机的方法,和任务性能驱动的方法。强化学习在社会机器人中的好处和挑战,关于他们是否使用主观和算法措施的论文的评估方法,在现实世界的强化学习的挑战和建议的解决方案的角度进行讨论,还有待探讨的点,包括迄今为止得到较少关注的方法也在本文中给出。因此,本文的目的是成为一个起点,研究人员有兴趣使用和应用强化学习方法在这个特定的研究领域。

英文摘要:

This article surveys reinforcement learning approaches in social robotics. Reinforcement learning is a framework for decision-making problems in which an agent interacts through trial-and-error with its environment to discover an optimal behavior. Since interaction is a key component in both reinforcement learning and social robotics, it can be a well-suited approach for real-world interactions with physically embodied social robots. The scope of the paper is focused particularly on studies that include social physical robots and real-world human-robot interactions with users. We present a thorough analysis of reinforcement learning approaches in social robotics. In addition to a survey, we categorize existent reinforcement learning approaches based on the used method and the design of the reward mechanisms. Moreover, since communication capability is a prominent feature of social robots, we discuss and group the papers based on the communication medium used for reward formulation. Considering the importance of designing the reward function, we also provide a categorization of the papers based on the nature of the reward. This categorization includes three major themes: interactive reinforcement learning, intrinsically motivated methods, and task performance-driven methods. The benefits and challenges of reinforcement learning in social robotics, evaluation methods of the papers regarding whether or not they use subjective and algorithmic measures, a discussion in the view of real-world reinforcement learning challenges and proposed solutions, the points that remain to be explored, including the approaches that have thus far received less attention is also given in the paper. Thus, this paper aims to become a starting point for researchers interested in using and applying reinforcement learning methods in this particular research field.
