New mathematical framework for online optimization and graph learning

This paper introduces new mathematical frameworks for understanding online optimization of piecewise-Lipschitz functions, specifically addressing root anti-concentration questions. The research provides sharp, dimension-free characterizations for feature curves and coefficients, improving upon previous methods by removing a $\sqrt{N}$ loss. The findings are applied to graph-learning scenarios, including a cost-sensitive Gaussian-RBF harmonic classifier and a polynomial-kernel model, both achieving improved regret bounds. AI
