GNN

Abbreviations / Acronyms / Synonyms:

graph neural network

Definitions:

  A neural network designed to process graph-structured data. GNNs perform optimizable transformations on graph attributes (e.g., nodes, edges, global context) while preserving graph symmetries such as permutation invariance. GNNs utilize a “graph-in, graph-out” architecture that takes an input graph with informa­tion and progressively transforms it into an output graph with the same connec­tivity as that of the input graph.
