摘要:

本文描述了一种新的方法来建立情感智能人机交互代理。该方法基于一个关键的社会学见解,该见解在过去20年中得到了发展和广泛验证,但尚未在人工智能中产生影响。这种观点认为,资源有限的人类会默认地采取行动来保持情感的一致性。人类在文化上分享了关于身份、行为和对象的基本情感,他们的行为是为了让互动过程中产生的短暂情感确认基本情感。人类寻求和创造的情况下,确认或符合,并避免和抑制的情况下,不确认或不一致,他们的文化共享的情感情绪。这种“情感控制原则”已被证明是人类行为的一个强有力的预测因素。在本文中,我们提出了一个概率和决策理论概括这一原则,我们演示了如何利用它来建立有效的智能人工代理。新的模型,称为贝叶斯法,可以保持多个假设的情绪同时作为一个概率分布,并可以利用一个显式的效用函数,使价值导向的行动选择。这使得模型能够通过了解人们的身份,使用情感控制原则预测他们的行为,并采取同时具有目标导向和情感敏感性的行动,与人们产生情感智能交互。我们证明了这一概括与一组模拟。然后,我们展示了我们的模型如何可以用作人工智能系统的情感“插件”,这些系统在两种不同的环境中与人类互动:考试练习助理(导师)和认知障碍人士的辅助设备。

英文摘要:

This paper describes a novel method for building affectively intelligent human-interactive agents. The method is based on a key sociological insight that has been developed and extensively verified over the last twenty years, but has yet to make an impact in artificial intelligence. The insight is that resource bounded humans will, by default, act to maintain affective consistency. Humans have culturally shared fundamental affective sentiments about identities, behaviours, and objects, and they act so that the transient affective sentiments created during interactions confirm the fundamental sentiments. Humans seek and create situations that confirm or are consistent with, and avoid and supress situations that disconfirm or are inconsistent with, their culturally shared affective sentiments. This "affect control principle" has been shown to be a powerful predictor of human behaviour. In this paper, we present a probabilistic and decision-theoretic generalisation of this principle, and we demonstrate how it can be leveraged to build affectively intelligent artificial agents. The new model, called BayesAct, can maintain multiple hypotheses about sentiments simultaneously as a probability distribution, and can make use of an explicit utility function to make value-directed action choices. This allows the model to generate affectively intelligent interactions with people by learning about their identity, predicting their behaviours using the affect control principle, and taking actions that are simultaneously goal-directed and affect-sensitive. We demonstrate this generalisation with a set of simulations. We then show how our model can be used as an emotional "plug-in" for artificially intelligent systems that interact with humans in two different settings: an exam practice assistant (tutor) and an assistive device for persons with a cognitive disability.
