Graph reweighting
WebJohnson's Algorithm uses the technique of "reweighting." If all edge weights w in a graph G = (V, E) are nonnegative, we can find the shortest paths between all pairs of vertices by running Dijkstra's Algorithm once from each vertex. ... Given a weighted, directed graph G = (V, E) with weight function w: E→R and let h: v→R be any function ... WebJun 21, 2024 · To solve these weaknesses, we design a novel GNN solution, namely Graph Attention Network with LSTM-based Path Reweighting (PR-GAT). PR-GAT can automatically aggregate multi-hop information, highlight important paths and filter out noises. In addition, we utilize random path sampling in PR-GAT for data augmentation.

In comparison with existing multiview registration methods, our method achieves 11% higher registration recall on the 3DMatch dataset and ~13% lower registration errors on the ScanNet dataset while …
WebMoreover, for partial and outlier matching, an adaptive reweighting technique is developed to suppress the overmatching issue. Experimental results on real-world benchmarks including natural image matching show our unsupervised method performs comparatively and even better against two-graph based supervised approaches. WebAug 26, 2014 · Graph reweighting Theorem. Given a label h(v) for each v V, reweight each edge (u, v) E by ŵ(u, v) = w(u, v) + h(u) – h(v). Then, all paths between the same two vertices are reweighted by the same amount. Proof. Let p = v1→ v2→ → vkbe a path in the grah Then, we have. Producing Nonnegative Weights
