New arXiv Papers Detail Advances in Convex Optimization Techniques

By PulseAugur Editorial · [5 sources] ·

Two new research papers on arXiv explore advancements in convex optimization. The first paper introduces a unified probing model for Online Convex Optimization (OCO) that can improve worst-case regret even with a sublinear and noisy probe budget. The second paper presents Hamiltonian dynamics-based algorithms that achieve accelerated convergence rates for smooth convex optimization, establishing Hamiltonian dynamics as a useful primitive for deterministic accelerated convex optimization.
