Vanila Graph Convolutional Network (GCN) (Kipf & Welling, 2016). The vanilla GCN is a first-order approximation of spectral graph convolutions. If one sets K= 1, 0 = 2, and 1 = 1 for Eq. 2, they obtain the convolution operation g (L) x = (I + D 1=2AD 1=2)x. Finally, by the renormalization trick, replacing matrix I + D 1=2AD 1=2 by a normalized ...

18.08.2021 · Despite the drawbacks of the original spectral graph convolution method, it has been developed a lot and has remained a quite competitive method in some applications, because spectral filters can better capture global complex patterns in graphs, which local methods like GCN ( Kipf & Welling, ICLR, 2017) cannot unless stacked in a deep network.

Unlike Spectral Convolution which takes a lot of time to compute, Spatial Convolutions are simple and have produced state of the art results on graph ...
