摘要:

尽管最近广泛关注可解释人工智能(XAI),但XAI方法计算的解释往往无法深入了解神经网络(NN)的功能。我们提出了一个新的框架,用于从NN获得(本地)解释,同时提供其内部工作的透明度,并展示了如何将其部署到各种神经架构和任务中。我们将我们的新解释统称为深度论证性解释(简称DAX),因为它们反映了底层NN的深层结构,并且它们是根据计算论证的概念定义的,这是一种符号AI形式,为解释提供了有用的推理抽象。我们根据经验评估DAX,表明它们具有很高的保真度和较低的计算成本。我们还进行了人体实验,表明DAX对人类来说是可以理解的,并且与他们的判断一致,同时在用户接受度方面也具有竞争力,与一些现有的XAI方法也具有争论精神。

英文摘要:

Despite the recent, widespread focus on eXplainable AI (XAI), explanations computed by XAI methods tend to provide little insight into the functioning of Neural Networks (NNs). We propose a novel framework for obtaining (local) explanations from NNs while providing transparency about their inner workings, and show how to deploy it for various neural architectures and tasks. We refer to our novel explanations collectively as Deep Argumentative eXplanations (DAXs in short), given that they reflect the deep structure of the underlying NNs and that they are defined in terms of notions from computational argumentation, a form of symbolic AI offering useful reasoning abstractions for explanation. We evaluate DAXs empirically showing that they exhibit deep fidelity and low computational cost. We also conduct human experiments indicating that DAXs are comprehensible to humans and align with their judgement, while also being competitive, in terms of user acceptance, with some existing approaches to XAI that also have an argumentative spirit.
