• Title: Learning Fair Representations via Rate-Distortion Maximization
• Authors: Somnath Basu Roy Chowdhury, Snigdha Chaturvedi
• Abstract summary: We present Fairness-aware Rate Maximization (FaRM), that removes demographic information by making representations of instances belonging to the same protected attribute class uncorrelated using the rate-distortion function. FaRM achieves state-of-the-art performance on several datasets, and learned representations leak significantly less protected attribute information against an attack by a non-linear probing network.

• Abstract: Text representations learned by machine learning models often encode undesirable demographic information of the user. Predictive models based on these representations can rely on such information resulting in biased decisions. We present a novel debiasing technique Fairness-aware Rate Maximization (FaRM), that removes demographic information by making representations of instances belonging to the same protected attribute class uncorrelated using the rate-distortion function. FaRM is able to debias representations with or without a target task at hand. FaRM can also be adapted to simultaneously remove information about multiple protected attributes. Empirical evaluations show that FaRM achieves state-of-the-art performance on several datasets, and learned representations leak significantly less protected attribute information against an attack by a non-linear probing network.

  We propose a novel debiasing framework for LVLMs by directly ablating biased attributes during text generation. Our method requires no training and a relatively small amount of representative biased outputs. Our experiments show that not only can we can minimize the propensity of LVLMs to generate text related to protected attributes, but we can even use synthetic data to inform the ablation.

  Collaborative filtering algorithms capture underlying consumption patterns, including the ones specific to particular demographics or protected information of users. These encoded biases can influence the decision of a recommendation system towards further separation of the contents provided to various demographic subgroups. In this work, we investigate the possibility and challenges of removing specific protected information of users from the learned interaction representations of a RS algorithm.

  We propose a semi-supervised fair representation learning approach based on adversarial variational autoencoder.

  Trained classification models can unintentionally lead to biased representations and predictions. Existing debiasing methods for classification models, such as adversarial training, are often expensive to train and difficult to optimise. We propose a method for mitigating bias by incorporating contrastive learning, in which instances sharing the same class label are encouraged to have similar representations.
