Webthe duality gap is zero for two-layer networks, we go beyond two-layer and study the convex duality for vector-output deep neural networks with linear activation and ReLU activation. … Webality gap computations to propose a simple strategy uni-fying both sequential and dynamic safe rules. We coined GAP SAFE rules such safe rules. The main contributions of this … 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. hamish todd aon
