A FedSage Algorithm

Referring to Section 4.3, FedSage+ includes two phases. We describe the aggregation operation below. We are going to define the kernel matrix of two nodes u,v V as follows. B.1 needs to calculate 1) a covariance matrix In Graphsage, this is equivalent to having K graph convectional layers. 's derivative is denoted as The generalization ability in the NTK regime and depends on the kernel matrix.
