Abstract

In the last few years, Artificial Intelligence (AI) systems have become increasingly widespread. Unfortunately, these systems can share many biases with human decision-making, including demographic biases. Often, these biases can be traced back to the data used for training, where large uncurated datasets have become the norm. Despite our awareness of these biases, we still lack general tools to detect, quantify, and compare them across different datasets. In this work, we propose DSAP (Demographic Similarity from Auxiliary Profiles), a two-step methodology for comparing the demographic composition of datasets. First, DSAP uses existing demographic estimation models to extract a dataset’s demographic profile. Second, it applies a similarity metric to compare the demographic profiles of different datasets. While these individual components are well-known, their joint use for demographic dataset comparison is novel and has not been previously addressed in the literature. This approach allows three key applications: the identification of demographic blind spots and bias issues across datasets, the measurement of demographic bias, and the assessment of demographic shifts over time. DSAP can be used on datasets with or without explicit demographic information, provided that demographic information can be derived from the samples using auxiliary models, such as those for image or voice datasets. To show the usefulness of the proposed methodology, we consider the Facial Expression Recognition task, where demographic bias has previously been found. The three applications are studied over a set of twenty datasets with varying properties. The code is available at https://github.com/irisdominguez/DSAP.
DSAP:通过数据集的人口统计学比较分析偏差
最近几年,人工智能(AI)系统日益普及。不幸的是,这些系统可能与人类决策存在许多共同的偏差,包括人口统计偏差。通常情况下,这些偏差可以追溯到用于训练的数据,未经整理的大型数据集已成为常态。尽管我们意识到了这些偏差,但仍然缺乏通用工具来检测、量化和比较不同数据集上的偏差。在这项工作中,我们提出了 DSAP(来自辅助档案的人口统计学相似性),这是一种分两步比较数据集人口组成的方法。首先,DSAP 使用现有的人口估计模型来提取数据集的人口特征。其次,它应用相似度量来比较不同数据集的人口构成。虽然这些单独的组成部分是众所周知的,但将它们联合起来用于人口数据集比较却是新颖的,以前的文献中从未涉及过。这种方法有三个关键应用:识别不同数据集的人口盲点和偏差问题、测量人口偏差以及评估人口随时间的变化。DSAP 可用于具有或不具有明确人口统计信息的数据集,前提是人口统计信息可通过辅助模型(如图像或语音数据集的辅助模型)从样本中导出。为了展示所提方法的实用性,我们考虑了面部表情识别任务,在该任务中,以前曾发现过人口统计学偏差。我们对 20 个不同属性的数据集进行了研究。代码见 https://github.com/irisdominguez/DSAP。
