Graphon and graph neural network stability
WebVideo 10.5 – Transferability of Graph Filters: Remarks. In this lecture, we introduce graphon neural networks (WNNs). We define them and compare them with their GNN counterpart. By doing so, we discuss their interpretations as generative models for GNNs. Also, we leverage the idea of a sequence of GNNs converging to a graphon neural … WebCourse Description. The course is organized in 4 sets of two lectures. The first set describes machine learning on graphs and provides an introduction to learning parameterizations. …
