摘要:

生成解释来解释其行为是机器人队友的基本能力。沟通帮助人类伙伴更好地了解情况,并保持对队友的信任。机器人生成解释的先前工作集中在提供其决策背后的推理。然而,这些方法没有注意到理解解释的认知要求。换句话说,虽然它们从解释者的角度提供了正确的解释,但方程式的被解释者部分被忽略了。在这项工作中,我们沿着这个方向解决一个重要方面,有助于更好地理解给定的解释,我们称之为解释的渐进性。渐进式解释通过限制每一步解释所需的认知努力来提高理解。因此,这种解释预计会更流畅,因此更容易理解。提出了渐进解释的一般公式。算法的基础上提供了几种替代量化的认知努力的解释,这是在一个标准的规划竞争域进行评估。

英文摘要:

Generating explanation to explain its behavior is an essential capability for a robotic teammate. Explanations help human partners better understand the situation and maintain trust of their teammates. Prior work on robot generating explanations focuses on providing the reasoning behind its decision making. These approaches, however, fail to heed the cognitive requirement of understanding an explanation. In other words, while they provide the right explanations from the explainer's perspective, the explainee part of the equation is ignored. In this work, we address an important aspect along this direction that contributes to a better understanding of a given explanation, which we refer to as the progressiveness of explanations. A progressive explanation improves understanding by limiting the cognitive effort required at each step of making the explanation. As a result, such explanations are expected to be smoother and hence easier to understand. A general formulation of progressive explanation is presented. Algorithms are provided based on several alternative quantifications of cognitive effort as an explanation is being made, which are evaluated in a standard planning competition domain.
