论文摘要
我们提出了一种歧视感知的学习方法,以提高偏见的面部识别算法的准确性和公平性。最受欢迎的面部识别基准假设主题分布,而无需大量关注其人口属性。在这项工作中,我们对基于深度学习的面部识别进行了全面的歧视感知实验。我们还提出了对面对生物识别技术的应用算法歧视的一般表述。这些实验包括树木流行的面部识别模型和三个公共数据库,这些数据库由以性别和种族为特征的不同人口组的64,000个身份组成。我们在实验上表明,基于最常用的面部数据库的学习过程导致了流行的预训练的深面模型,这些模型呈现出强烈的算法歧视。我们最终根据流行的三胞胎损失函数和敏感的三重态生成器提出了一种歧视感知的学习方法,敏感的损失。我们的方法是预先训练的网络的附加组件,并用于在平均准确性和公平性方面提高其性能。该方法显示的结果与最先进的偏见网络相当,并且代表了前进的一步,以防止自动系统歧视效应。
We propose a discrimination-aware learning method to improve both accuracy and fairness of biased face recognition algorithms. The most popular face recognition benchmarks assume a distribution of subjects without paying much attention to their demographic attributes. In this work, we perform a comprehensive discrimination-aware experimentation of deep learning-based face recognition. We also propose a general formulation of algorithmic discrimination with application to face biometrics. The experiments include tree popular face recognition models and three public databases composed of 64,000 identities from different demographic groups characterized by gender and ethnicity. We experimentally show that learning processes based on the most used face databases have led to popular pre-trained deep face models that present a strong algorithmic discrimination. We finally propose a discrimination-aware learning method, Sensitive Loss, based on the popular triplet loss function and a sensitive triplet generator. Our approach works as an add-on to pre-trained networks and is used to improve their performance in terms of average accuracy and fairness. The method shows results comparable to state-of-the-art de-biasing networks and represents a step forward to prevent discriminatory effects by automatic systems.
