Graph convolution kernel
WebSep 28, 2024 · In this paper, we use a modified Markov Diffusion Kernel to derive a variant of GCN called Simple Spectral Graph Convolution (SSGC). Our spectral analysis shows that our simple spectral graph convolution used in SSGC is a trade-off of low- and high-pass filter bands which capture the global and local contexts of each node. We provide … WebGraph kernel. In structure mining, a graph kernel is a kernel function that computes an inner product on graphs. [1] Graph kernels can be intuitively understood as functions …
