Achieving Fair AI Without Sacrificing Accuracy
This study tests SA-DROâs effectiveness in reducing bias in DP-based fair learning models. Results show that SA-DRO minimizes bias toward majority attributes while maintaining accuracy. In federated learning, SA-DRO improves...
How to Test for AI Fairness
This study tests AI fairness using the COMPAS, Adult, and CelebA datasets, applying DP-based learning methods. Various classifiers, including logistic regression and neural networks, assess how well models handle demographic...
The Limits of Demographic Parity in AI Models
DP-based fair learning can introduce unintended biases favoring majority groups. This section explores the mathematical proofs behind these biases and introduces a distributionally robust optimization (DRO) approach to mitigate them.
How to Measure Fairness in AI Models
Fair supervised learning requires meeting fairness criteria, such as demographic parity. This section reviews standard fairness measures and dependence metrics used to detect and mitigate bias in AI models.
What to Do When âFairâ AI Delivers Unfair Results
Demographic parity (DP) fairness methods in AI can unintentionally favor majority groups, leading to bias. This study introduces SA-DRO, an optimization technique that reduces this bias by adjusting for imbalanced...
