Inspired by the “LineGraph” in graph theory, Jiang et al.36 proposed Convolution with Edge-Node Switching graph neural network (CensNet). This is a kind of network that can alternately learn node embedding and edge embedding. CensNet builds an auxiliary graph by changing the nodes in the ...
Graph-based theory has been proved a powerful tool to signal processing, as the graph representations have the ability to exploit the interrelations among the signals or segments of signals12. Hence, graphs can be based on the statistical information of the signals or even their structural one, ...

To overcome this issue, PPNP, personalized propagation of neural predictions, took inspiration from personal PageRank and classical graph theory to perform infinitely many propagation steps in an implicit manner, thus considering a large neighbourhood without encountering oversmoothing [31]. Cell graphs ...

We propose a new type of supervised visual machine learning classifier, GSNAc, based on graph theory and social network analysis techniques. In a previous study, we employed social network analysis techniques and introduced a novel classification model (
