AI总结:

本文提出了一种结合CAIPI和RRR的混合XIL方法,用于缓解视觉性别分类中的偏见和伪相关性,通过用户反馈提升模型公平性和透明度。

摘要:

可解释性交互式学习(XIL)通过让用户对模型的解释提供反馈,从而引导模型训练,帮助模型关注与用户视角相关的预测相关特征。在本研究中,我们探讨了这种学习范式在缓解视觉分类器中的偏见和伪相关性方面的能力,特别是在容易产生数据偏见的场景中,如性别分类。我们研究了两种方法上不同的最新XIL策略,即CAIPI和Right for the Right Reasons(RRR),以及一种结合这两种策略的新混合方法。结果通过比较使用梯度加权类激活映射(GradCAM)和有界日志it注意(BLA)生成的分割掩码进行定量评估。实验结果表明,这些方法在(i)引导ML模型关注相关图像特征,特别是当使用CAIPI时,以及(ii)减少模型偏见(即平衡男性和女性预测的误分类率)方面是有效的。我们的分析进一步支持了XIL方法在提高性别分类器公平性方面的潜力。总体而言,XIL获得的增加透明度和公平性导致了轻微的性能下降,除了CAIPI外,后者显示出甚至可能提高分类准确性的潜力。

英文摘要:

Explanatory interactive learning (XIL) enables users to guide model training in machine learning (ML) by providing feedback on the model's explanations, thereby helping it to focus on features that are relevant to the prediction from the user's perspective. In this study, we explore the capability of this learning paradigm to mitigate bias and spurious correlations in visual classifiers, specifically in scenarios prone to data bias, such as gender classification. We investigate two methodologically different state-of-the-art XIL strategies, i.e., CAIPI and Right for the Right Reasons (RRR), as well as a novel hybrid approach that combines both strategies. The results are evaluated quantitatively by comparing segmentation masks with explanations generated using Gradient-weighted Class Activation Mapping (GradCAM) and Bounded Logit Attention (BLA). Experimental results demonstrate the effectiveness of these methods in (i) guiding ML models to focus on relevant image features, particularly when CAIPI is used, and (ii) reducing model bias (i.e., balancing the misclassification rates between male and female predictions). Our analysis further supports the potential of XIL methods to improve fairness in gender classifiers. Overall, the increased transparency and fairness obtained by XIL leads to slight performance decreases with an exception being CAIPI, which shows potential to even improve classification accuracy.
