图像分类中的人类与当前可解释AI的解释策略对比

Explanation Strategies for Image Classification in Humans vs. Current Explainable AI

Ruoxi Qi, Yueyuan Zheng, Yi Yang, Caleb Chen Cao, Janet H. Hsiao

AI总结:

本研究比较图像分类中人类与XAI的解释策略,发现人类采用聚焦或探索性两种策略,突出可观测因果性特征的XAI方法更匹配人类解释。

摘要:

可解释AI(XAI)方法提供对AI模型的解释,但我们对它们与人类解释的比较仍了解有限。在图像分类中,我们发现人类在解释时比分类任务本身采用更具探索性的注意策略。通过聚类识别出两种代表性解释策略:一种是对前景物体进行聚焦视觉扫描,伴随更多概念性解释,这对推断类别标签具有诊断性;另一种是探索性扫描,伴随更多视觉解释,在有效性上评分更高。有趣的是,XAI显著性图解释与人类的探索性注意策略相似度最高,而通过扰动引发可观测因果性以突出判别性特征的解释,比突出与更高类别分数相关的内部特征的解释与人类策略相似度更高。因此,人类在解释的信息和策略使用上存在差异,突出可观测因果性信息的XAI方法更匹配人类解释,可能对用户更易理解。

英文摘要:

Explainable AI (XAI) methods provide explanations of AI models, but our understanding of how they compare with human explanations remains limited. In image classification, we found that humans adopted more explorative attention strategies for explanation than the classification task itself. Two representative explanation strategies were identified through clustering: One involved focused visual scanning on foreground objects with more conceptual explanations diagnostic for inferring class labels, whereas the other involved explorative scanning with more visual explanations rated higher for effectiveness. Interestingly, XAI saliency-map explanations had the highest similarity to the explorative attention strategy in humans, and explanations highlighting discriminative features from invoking observable causality through perturbation had higher similarity to human strategies than those highlighting internal features associated with higher class score. Thus, humans differ in information and strategy use for explanations, and XAI methods that highlight features informing observable causality match better with human explanations, potentially more accessible to users.
