WebTo this end, we propose HDHGR, a homophily-oriented deep heterogeneous graph rewiring approach that modifies the HG structure to increase the performance of HGNN. We theoretically verify HDHGR. In addition, experiments on real-world HGs demonstrate the effectiveness of HDHGR, which brings at most more than 10% relative gain. WebGraph rewiring [2, 7, 14, 29] is a kind of method that decouples the input graph from the graph for message passing and boost the performance of GNN on node classification tasks via changing the message passing structure. Many works have utilized graph rewiring for different tasks. However, most existing graph rewiring

WebJun 15, 2024 · Graph rewiring and graph pooling have been proposed in the literature as solutions to address these limitations. However, most state-of-the-art graph rewiring methods fail to preserve the global topology of the graph, are neither differentiable nor inductive, and require the tuning of hyper-parameters. WebMay 15, 2024 · The Watts-Strogatz model is a random graph generation model that produces graphs with small-world properties, including short average path lengths and high clustering.To check the simulation of a small world model, this website is very helpful. The generation of a Watts-Strogatz random graph is called the rewiring process:. Build a … WebTL;DR: GAP-Layer is a GNN Layer which is able to rewire a graph in an inductive an parameter-free way optimizing the spectral gap (minimizing or maximizing the bottleneck size), learning a differentiable way to compute the Fiedler vector and the Fiedler value of the graph.
