Researchers have introduced a novel approach to group fairness in machine learning by framing it as a bargaining problem among subpopulations. This game-theoretic perspective suggests that existing methods like minimizing worst-group loss are equivalent to classical bargaining solutions. The proposed method, relative improvement, measures the ratio of actual risk reduction to potential reduction from a baseline predictor, aligning with the Kalai-Smorodinsky solution and offering scale invariance and individual monotonicity.
