Towards Equal Opportunity Fairness through Adversarial Learning

Abstract

Adversarial training is a common approach for bias mitigation in natural language processing. Although most work on debiasing is based around the equal opportunity criterion, it is not explicitly captured in standard adversarial training. In this paper, we propose an augmented discriminator for adversarial training, which takes the target class as input to create richer features and more explicitly model equal opportunity. Experimental results over two datasets show that our method substantially improves over standard adversarial debiasing methods, in terms of the performance--fairness trade-off.
