A new research paper published on arXiv explores the relationship between convex learning and non-affine aggregation methods. The study proves that maintaining monotonicity in gradient updates, crucial for convergence and generalization in first-order convex learning, is only possible with positively affine aggregation rules. The research demonstrates that non-affine aggregation, often used to enforce constraints like privacy or fairness, fundamentally hinders steady convergence and degrades algorithmic stability. The findings offer a theoretical framework to explain failures in modern learning systems and suggest conditions for restoring monotonicity. AI
