The rapid growth of healthcare data and advances in computational power have accelerated the adoption of artificial intelligence (AI) in medicine.
To address potential disparities in healthcare AI, a novel gradient reconciliation framework called FairGrad has been proposed.
FairGrad balances predictive performance and multi-attribute fairness optimization in healthcare AI models by projecting each gradient vector onto the orthogonal plane of the others.
FairGrad achieved statistically significant improvements in multi-attribute fairness metrics while maintaining competitive predictive accuracy in real-world healthcare datasets.
