Metrics and methods for a systematic comparison of fairness-aware machine learning algorithms

no code implementations8 Oct 2020 Gareth P. Jones, James M. Hickey, Pietro G. Di Stefano, Charanpal Dhanjal, Laura C. Stoddart, Vlasios Vasileiou

We found that fairness-unaware algorithms typically fail to produce adequately fair models and that the simplest algorithms are not necessarily the fairest ones.

Fairness by Explicability and Adversarial SHAP Learning

no code implementations11 Mar 2020 James M. Hickey, Pietro G. Di Stefano, Vlasios Vasileiou

To satisfy this definition, we develop a framework for mitigating model bias using regularizations constructed from the SHAP values of an adversarial surrogate model.

Counterfactual fairness: removing direct effects through regularization

no code implementations25 Feb 2020 Pietro G. Di Stefano, James M. Hickey, Vlasios Vasileiou

We develop regularizations to tackle classical fairness measures and present a causal regularization that satisfies our new fairness definition by removing the impact of unprivileged group variables on the model outcomes as measured by the CDE.
