摘要:

存在多种方法来解释图像分类模型。然而,与简单地比较各种输入和模型各自的预测相比,它们是否为用户提供了任何好处仍不清楚。我们进行了一项用户研究(N=240),以测试这样的基线解释技术对基于概念和反事实的解释。为此,我们贡献了一个合成数据集生成器,能够偏置单个属性并量化它们与模型的相关性。在一项研究中,我们评估参与者是否能够识别与地面事实相比的相关属性集。我们的研究结果表明,基线优于基于概念的解释。来自可逆神经网络的反事实解释与基线相似。尽管如此,它们仍然允许用户更准确地识别某些属性。我们的研究结果强调了衡量用户对模型偏差的推理能力的重要性,而不是仅仅依赖于技术评估或代理任务。我们开源了我们的研究和数据集,因此它可以作为未来研究的蓝图。有关代码,请参见https://github.com/berleon/do_users_benefit_from_interpretable_vision

英文摘要:

A variety of methods exist to explain image classification models. However, whether they provide any benefit to users over simply comparing various inputs and the model's respective predictions remains unclear. We conducted a user study (N=240) to test how such a baseline explanation technique performs against concept-based and counterfactual explanations. To this end, we contribute a synthetic dataset generator capable of biasing individual attributes and quantifying their relevance to the model. In a study, we assess if participants can identify the relevant set of attributes compared to the ground-truth. Our results show that the baseline outperformed concept-based explanations. Counterfactual explanations from an invertible neural network performed similarly as the baseline. Still, they allowed users to identify some attributes more accurately. Our results highlight the importance of measuring how well users can reason about biases of a model, rather than solely relying on technical evaluations or proxy tasks. We open-source our study and dataset so it can serve as a blue-print for future studies. For code see, https://github.com/berleon/do_users_benefit_from_interpretable_vision
