Graph reduction
WebJan 1, 2024 · In the present paper, we introduce a novel graph reduction method that learns the relevant features of the graph topology by means of Graph Neural Networks (GNN). Research on GNNs is a rapidly emerging field in structural pattern recognition [14, 15]. The general idea of GNNs is to learn vector representations for nodes and/or (sub … WebMar 1, 2024 · What you want to do is called contraction of vertices which have exactly 2 neighbours, i.e. that have degree 2. For implementing this, do the following: while exists vertex v with degree 2: - remove v and the …
