A causal framework for discovering and removing direct and indirect discrimination

L Zhang, Y Wu, X Wu - arXiv preprint arXiv:1611.07509, 2016 - arxiv.org
Anti-discrimination is an increasingly important task in data science. In this paper, we investigate
the problem of discovering both direct and indirect discrimination from the historical data…

Pc-fairness: A unified framework for measuring causality-based fairness

Y Wu, L Zhang, X Wu, H Tong - Advances in neural …, 2019 - proceedings.neurips.cc
A recent trend of fair machine learning is to define fairness as causality-based notions which
concern the causal connection between protected attributes and decisions. However, one …

On discrimination discovery and removal in ranked data using causal graph

Y Wu, L Zhang, X Wu - Proceedings of the 24th ACM SIGKDD …, 2018 - dl.acm.org
Predictive models learned from historical data are widely used to help companies and

On convexity and bounds of fairness-aware classification

Y Wu, L Zhang, X Wu - The World Wide Web Conference, 2019 - dl.acm.org
In this paper, we study the fairness-aware classification problem by formulating it as a
constrained optimization problem. Several limitations exist in previous works due to the lack of a …

[PDF][PDF] Situation Testing-Based Discrimination Discovery: A Causal Inference Approach.

L Zhang, Y Wu, X Wu - IJCAI, 2016 - researchgate.net
