WebLightGCN The basic idea of GCN is to learning representation for nodes by smoothing features over the graph (GCN; SGCN) . To achieve this, it performs graph convolution iteratively, i.e., aggregating the features of neighbors as the new representation of a target node. Such neighborhood aggregation can be abstracted as: (2)
