连续最优运输的公平性

Fairness with Continuous Optimal Transport

Silvia Chiappa, Aldo Pacchiano

摘要:

虽然最优传输(OT)越来越多地被认为是一个强大的和灵活的方法来处理公平性问题,目前的OT公平性方法仅限于使用离散OT。在本文中,我们利用最新的进展,从OT文献介绍了一个随机梯度公平方法的基础上,连续OT的对偶制定。我们表明,这种方法提供了优越的性能,离散OT方法时,很少的数据可用于解决OT问题,否则类似的性能。我们还表明,连续和离散OT方法都能够不断调整模型参数,以适应ML系统在现实世界中可能出现的不同程度的不公平。

英文摘要:

Whilst optimal transport (OT) is increasingly being recognized as a powerful and flexible approach for dealing with fairness issues, current OT fairness methods are confined to the use of discrete OT. In this paper, we leverage recent advances from the OT literature to introduce a stochastic-gradient fairness method based on a dual formulation of continuous OT. We show that this method gives superior performance to discrete OT methods when little data is available to solve the OT problem, and similar performance otherwise. We also show that both continuous and discrete OT methods are able to continually adjust the model parameters to adapt to different levels of unfairness that might occur in real-world applications of ML systems.
