Greedy relaxation
WebJan 23, 2024 · In this context, we consider a simpler, but more effective, substitute that uses minimal feedback, which we call Decoupled Greedy Learning (DGL). It is based on a greedy relaxation of the joint training objective, recently shown to be effective in the context of Convolutional Neural Networks (CNNs) on large-scale image classification. WebApr 14, 2024 · Because the ratio of greedy profit to an LP relaxation-based upper bound for small instances was 86%, a corresponding value of 92% for large instances suggests that the greedy heuristic’s performance did not deteriorate with the problem size. We then conduct a variety of computational experiments to provide managerial insights to the …
