WebGCN for semi-supervised learning, is schematically depicted in Figure 1. 3.1 EXAMPLE In the following, we consider a two-layer GCN for semi-supervised node classification on a graph with a symmetric adjacency matrix A(binary or weighted). We first calculate A^ = D~ 12 A~D~ 1 2 in a pre-processing step. Our forward model then takes the simple ... WebMar 26, 2024 · Questions & Help. So I am not sure how I would implement a batchnorm layer if I am using a GCN. After a Convolution I would get a matrix of size [nodes_per_graph*batchsize, features].But the nodes_per_graph differ between graphs so some batches haves more rows than others.. Now would I still perform a normilaization …
