Abstract

This thesis advances intersectional group fairness in machine learning by addressing key challenges including under-representation, fairness–utility trade-offs, and structural disparities across groups. It introduces three novel contributions: (1) a conditional generative modelling approach with transfer learning to improve fairness for under-represented intersectional groups; (2) a unified framework that combines fair representation learning with fairness regularisation to preserve fairness during downstream task optimisation; and (3) a method to enforce structural similarity in the learned representation space, enabling fairness generalisation across intersectional groups even when similarity is lacking in the original feature space.
