摘要:

用实例来解释是向AI决策提供合理说明的一种直观方式。然而,当许多特征差异较大时,理解决策值如何相对于实例变化具有挑战性。我们借鉴房地产估价中使用可比性(即具有已知价值的实例)进行比较的方法。通过假设性地调整每个可比实例的属性,并相应地根据因素改变价值,使估计更加准确。我们提出了可比性XAI,用于提供与实例相关的AI解释,通过追踪从每个可比实例到主体的反事实变化,每次只调整一个属性,单调地沿AI特征空间进行。在建模和用户研究中,经过调整的可比实例在XAI的忠实性、精度、用户准确性以及最窄的不确定性界限方面均优于线性回归、线性调整的可比实例或未调整的可比实例。这项工作为使用基于实例的解释来提高用户对AI决策的理解提供了新的分析基础。

英文摘要:

Explaining with examples is an intuitive way to justify AI decisions. However, it is challenging to understand how a decision value should change relative to the examples with many features differing by large amounts. We draw from real estate valuation that uses Comparables-examples with known values for comparison. Estimates are made more accurate by hypothetically adjusting the attributes of each Comparable and correspondingly changing the value based on factors. We propose Comparables XAI for relatable example-based explanations of AI with Trace adjustments that trace counterfactual changes from each Comparable to the Subject, one attribute at a time, monotonically along the AI feature space. In modelling and user studies, Trace-adjusted Comparables achieved the highest XAI faithfulness and precision, user accuracy, and narrowest uncertainty bounds compared to linear regression, linearly adjusted Comparables, or unadjusted Comparables. This work contributes a new analytical basis for using example-based explanations to improve user understanding of AI decisions.
