摘要:

考虑到现实世界中非结构化领域的复杂性,设计包含处理自治系统可能遇到的所有可能场景所需的每个功能的模型通常是不可能或不切实际的。一个自治系统要在这些领域中可靠,它应该有能力提高其在线能力。在本文中,我们提出了一种方法,用于提高系统的能力,在其部署过程中。我们特别关注一类被称为能力感知系统的半自治系统,它们对自己的能力进行建模-在任何给定情况下使用的最佳自主程度-并随着时间的推移从与人类权威的互动中获得的反馈中学习这种能力。我们的方法利用这种反馈来识别系统初始模型中缺失的重要状态特征,并将其纳入其状态表示中。其结果是一个更好地预测人类参与的代理,从而提高其能力和可靠性,并因此提高其整体性能。

英文摘要:

Given the complexity of real-world, unstructured domains, it is often impossible or impractical to design models that include every feature needed to handle all possible scenarios that an autonomous system may encounter. For an autonomous system to be reliable in such domains, it should have the ability to improve its competence online. In this paper, we propose a method for improving the competence of a system over the course of its deployment. We specifically focus on a class of semi-autonomous systems known as competence-aware systems that model their own competence -- the optimal extent of autonomy to use in any given situation -- and learn this competence over time from feedback received through interactions with a human authority. Our method exploits such feedback to identify important state features missing from the system's initial model, and incorporates them into its state representation. The result is an agent that better predicts human involvement, leading to improvements in its competence and reliability, and as a result, its overall performance.
