Web20 jul. 2024 · GCNs are used for semi-supervised learning on the graph. GCNs use both node features and the structure for the training. The main idea of the GCN is to take the weighted average of all neighbors’ node features (including itself): Lower-degree nodes get larger weights. Webvariable, edge features could be continuous, e.g., strengths, or multi-dimensional. GCNs can utilize one-dimensional real-valued edge features, e.g., edge weights, but the edge …
