WebSep 7, 2024 · The edge homophily ratio \(h = \frac{ {(u, v):(u, v)\in \mathcal {E} \wedge y_u = y_v} }{ \mathcal {E} }\) is the fraction of edges in a graph which connect nodes that have the same class label, i.e., intra-class edges . The homophily ratio h is a measure of the graph homophily level and we have \(h \in [0, 1]\). WebAug 24, 2024 · torch_geometric.utils.homophily_ratio seems to output a single value for a batch of graphs. I'd like to extract this value on a per-graph level, such that instead of a single number, the output would be [batch_size,1]. I realize I could simply calculate this quantity when the graphs are constructed, as a preprocessing step, but for my specific ... ff O\\u0027Hare

WebTherefore, in response to dealing with heterophilic graphs, researchers first defined the homophily ratio (HR) by the ratio of edges connecting nodes with the same class … WebSep 27, 2024 · The extended homophily ratio is the sum of edge weight where connected region nodes share the same crime label divided by the sum of the edge weight considering whole neighbor nodes. Intuitively, the extended homophily ratio measures the probability that neighbor region nodes share similar crime patterns, ...
