Progress in duality gap has deteriorated
WebJun 8, 2024 · Our analyses suggest that: 1) the common strategy of first fine-tuning $\lambda$ on small networks and then directly use it for wide model training could lead to deteriorated model robustness; 2) one needs to properly enlarge $\lambda$ to unleash the robustness potential of wider models fully. WebSep 4, 2024 · Duality appears in many linear and nonlinear optimization models. In many of these applications we can solve the dual in cases when solving the primal is more …

WebMar 6, 2024 · Abstract. In this paper we consider the duality gap function g that measures the difference between the optimal values of the primal problem and of the dual problem in linear programming and in linear semi-infinite programming. We analyze its behavior when the data defining these problems may be perturbed, considering seven different scenarios. WebAbstract. It is well known that the duality theory for linear programming (LP) is powerful and elegant and lies behind algorithms such as simplex and interior-point methods. However, …

We have seen how weak duality allows to form a convex optimization problem that provides a lower bound on the original (primal) problem, even when the latter is non-convex. The duality gap is the non-negative number p d.
