摘要:

近年来,人们对机器学习系统的兴趣激增,这些系统可以为其预测或决策提供人类可理解的理由。然而,究竟什么样的解释是真正的人类解释仍然知之甚少。这项工作推进了我们对是什么使解释在特定的验证背景下可解释的理解。假设我们有一个预测X的机器学习系统,我们为这个预测X提供了基本原理。给定一个输入、一个解释和一个输出,输出是否与输入和假设的基本原理一致?通过一系列的用户研究,我们确定了什么样的复杂性增加对人类验证原理所需的时间影响最大,哪些似乎相对不敏感。

英文摘要:

Recent years have seen a boom in interest in machine learning systems that can provide a human-understandable rationale for their predictions or decisions. However, exactly what kinds of explanation are truly human-interpretable remains poorly understood. This work advances our understanding of what makes explanations interpretable in the specific context of verification. Suppose we have a machine learning system that predicts X, and we provide rationale for this prediction X. Given an input, an explanation, and an output, is the output consistent with the input and the supposed rationale? Via a series of user-studies, we identify what kinds of increases in complexity have the greatest effect on the time it takes for humans to verify the rationale, and which seem relatively insensitive.
