Overview of GNNs

A Graph Neural Network (GNN) extends CNN learning to graph data. A graph can be represented as a combination of nodes and edges, where nodes represent the features of the graph and edges joins adjacent nodes, as shown in the following image:

In this image, the nodes are illustrated by solid white points and the edges by the lines joining the points.

The following equations describe the key parameters of the graph:
