AI总结:

本文综述服务机器人中的知识表示,梳理其收集、表示与复现方式,区分于机器学习等模型,并探讨设计有效知识表示的关键原则。

摘要:

在服务机器人领域,研究人员投入了大量精力来学习、理解并将运动表示为机器人执行任务的操控动作。机器人学习和问题解决的任务非常广泛,因为它整合了多种任务,如目标检测、活动识别、任务/运动规划、定位、知识表示与检索,以及感知/视觉与机器学习技术的交织。在本文中,我们仅聚焦于知识表示,特别是研究人员在过去几十年中如何典型地收集、表示和复现知识以解决问题。根据知识表示的定义,我们讨论了此类表示与近年来被广泛引入和研究的实用学习模型(如机器学习、深度学习、概率建模和语义图结构)之间的关键区别。在概述这些工具的同时,我们讨论了机器人学习中存在的问题,以及它们如何被构建和使用作为解决方案、技术或发展(如果有的话)来助力解决这些问题。最后,我们讨论了在设计有效知识表示时应考虑的关键原则。

英文摘要:

Within the realm of service robotics, researchers have placed a great amount of effort into learning, understanding, and representing motions as manipulations for task execution by robots. The task of robot learning and problem-solving is very broad, as it integrates a variety of tasks such as object detection, activity recognition, task/motion planning, localization, knowledge representation and retrieval, and the intertwining of perception/vision and machine learning techniques. In this paper, we solely focus on knowledge representations and notably how knowledge is typically gathered, represented, and reproduced to solve problems as done by researchers in the past decades. In accordance with the definition of knowledge representations, we discuss the key distinction between such representations and useful learning models that have extensively been introduced and studied in recent years, such as machine learning, deep learning, probabilistic modelling, and semantic graphical structures. Along with an overview of such tools, we discuss the problems which have existed in robot learning and how they have been built and used as solutions, technologies or developments (if any) which have contributed to solving them. Finally, we discuss key principles that should be considered when designing an effective knowledge representation.
