Graph optimal transport
WebHere we present Graph Optimal Transport Networks (GOTNet) to capture long-range dependencies without increasing the depths of GNNs. Specifically, we perform k-Means clustering on nodes’ GNN embeddings to obtain graph-level representations (e.g., centroids). We then compute node-centroid attentions, which enable long-range … WebJul 21, 2011 · 4. Finding routes for a car is pretty easy: you store a weighted graph of all the roads and you could use Djikstra's algorithm. A bus route is less obvious. It may be less obvious, but the reality is that it's merely another dimension to the car problem, with the addition of infinite cost calculation.
