摘要:

很少有可解释的人工智能(XAI)研究考虑用户对解释的理解可能会根据他们对要解释的领域的了解程度(即,他们的专业知识是否不同)。然而,专业知识是大多数高风险人类决策的关键方面(例如,了解实习医生与有经验的顾问的不同之处)。因此,本文报告了一项新的用户研究(N=96),通过深度学习黑盒分类器的例子,研究人们在某个领域的专业知识如何影响他们对事后解释的理解。结果表明,人们对正确和不正确分类的解释的理解在几个维度上发生了巨大变化(例如,响应时间,对正确性和有用性的感知),当所考虑的基于图像的域是熟悉的(即,MNIST),而不是不熟悉的(即,Kannada MNIST)。更广泛的影响,这些新的发现XAI战略进行了讨论。

英文摘要:

Very few eXplainable AI (XAI) studies consider how users understanding of explanations might change depending on whether they know more or less about the to be explained domain (i.e., whether they differ in their expertise). Yet, expertise is a critical facet of most high stakes, human decision making (e.g., understanding how a trainee doctor differs from an experienced consultant). Accordingly, this paper reports a novel, user study (N=96) on how peoples expertise in a domain affects their understanding of post-hoc explanations by example for a deep-learning, black box classifier. The results show that peoples understanding of explanations for correct and incorrect classifications changes dramatically, on several dimensions (e.g., response times, perceptions of correctness and helpfulness), when the image-based domain considered is familiar (i.e., MNIST) as opposed to unfamiliar (i.e., Kannada MNIST). The wider implications of these new findings for XAI strategies are discussed.
