Enabling Robots to Infer how End-Users Teach and Learn through Human-Robot Interaction

摘要:

在人机交互(HRI)中,我们希望机器人理解我们,我们希望直观地理解机器人。为了与机器人进行交流和理解,我们可以利用交互,人类和机器人可以观察彼此的行为。然而,人类和机器人应该如何解释这些动作并不总是很清楚:一个给定的交互可能意味着几个不同的事情。在当今的最先进技术中,机器人为人类分配一个单一的交互策略,并根据这个固定的策略向人类学习或教导人类。相反,我们在这里认识到,不同的用户以不同的方式进行交互,因此一种尺寸并不适合所有人。因此,我们认为,机器人应该保持一个分布在可能的人类互动策略,然后推断每个终端用户如何在任务过程中进行交互。当机器人不确定人类的交互策略时,我们正式定义了学习和教学,并使用贝叶斯推理推导出这两个问题的解决方案。在示例和基准模拟中,我们表明我们的个性化方法优于保持固定交互策略的标准方法。

英文摘要:

During human-robot interaction (HRI), we want the robot to understand us, and we want to intuitively understand the robot. In order to communicate with and understand the robot, we can leverage interactions, where the human and robot observe each other's behavior. However, it is not always clear how the human and robot should interpret these actions: a given interaction might mean several different things. Within today's state-of-the-art, the robot assigns a single interaction strategy to the human, and learns from or teaches the human according to this fixed strategy. Instead, we here recognize that different users interact in different ways, and so one size does not fit all. Therefore, we argue that the robot should maintain a distribution over the possible human interaction strategies, and then infer how each individual end-user interacts during the task. We formally define learning and teaching when the robot is uncertain about the human's interaction strategy, and derive solutions to both problems using Bayesian inference. In examples and a benchmark simulation, we show that our personalized approach outperforms standard methods that maintain a fixed interaction strategy.
