Interacting systems with competition. Weband then an optimal match is mapping x˙ X(k) 7!y˙ Y(k), i.e. an optimal transport is ˙= ˙Y ˙ 1 X. The total computational cost is thus O(nlog(n)) using for instance quicksort algorithm. Note that if ’: R !R is an increasing map, with a change of variable, one can apply this technique to cost of the form h(j’(x) ’(y)j).

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 … WebJun 25, 2024 · The learned attention matrices are also dense and lacks interpretability.
