Researchers have developed a new algorithm called COVA-FC to address challenges in fair clustering, particularly when dealing with multiple sensitive attributes that define numerous subgroups. Existing methods struggle with the computational expense and numerical instability that arise as the number of subgroups increases exponentially. COVA-FC introduces a covariance-based surrogate for a subgroup-fairness gap, enabling efficient gradient-based optimization. The framework also extends to capture a subgroup-marginal-fairness gap, and experiments demonstrate its competitive cost-fairness trade-offs and improved computational efficiency compared to existing baselines.
