Fairness of decision-making algorithms is an increasingly important issue.
New efficient method for fair spectral clustering (Fair SC) presented by casting the Fair SC problem within the difference of convex functions framework.
Introduces a novel variable augmentation strategy and employs an alternating direction method of multipliers type of algorithm adapted to DC problems.
Numerical experiments demonstrate the effectiveness of the approach on synthetic and real-world benchmarks, showing significant speedups in computation time over prior art.
