Greedy relaxation

WebJun 12, 2024 · I'm wondering if the normal Dijkstra algorithm (Greedy + Relaxation) still applies in the case. Because we don't know the full graph, the shortest path to a node might haven't been explored yet, and exist in the unknown part. (That's my biggest concern). I hope my explanations are clear enough, thank you very much! WebIt 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. We consider an optimization of this objective that permits us to decouple the layer training, allowing for layers or modules in networks to be trained with ...
