论文摘要
随着计算机视觉应用程序的最新增长,尚未探索它们的公平和公正性问题。有大量证据表明,训练数据中存在的偏差反映在模型中,甚至放大。图像数据集的许多以前的方法是偏见的,包括基于增强数据集的模型,在计算上实现了昂贵。在这项研究中,我们提出了一个快速有效的模型,以通过重建并最大程度地减少预期变量之间的统计依赖性来消除图像数据集。我们的架构包括重建图像的U-NET,并结合了预训练的分类器,该分类器惩罚了目标属性和受保护属性之间的统计依赖性。我们在Celeba数据集上评估了我们提出的模型,将结果与最先进的偏见方法进行了比较,并表明该模型实现了有希望的公平性 - 准确性组合。
With the recent growth in computer vision applications, the question of how fair and unbiased they are has yet to be explored. There is abundant evidence that the bias present in training data is reflected in the models, or even amplified. Many previous methods for image dataset de-biasing, including models based on augmenting datasets, are computationally expensive to implement. In this study, we present a fast and effective model to de-bias an image dataset through reconstruction and minimizing the statistical dependence between intended variables. Our architecture includes a U-net to reconstruct images, combined with a pre-trained classifier which penalizes the statistical dependence between target attribute and the protected attribute. We evaluate our proposed model on CelebA dataset, compare the results with a state-of-the-art de-biasing method, and show that the model achieves a promising fairness-accuracy combination.
