Abstract

The invention provides a graph neural network training method, graph neural network equipment and device and a medium. The graph neural network training method comprises the steps: obtaining graph structure data of a graph neural network, the graph structure data comprising representation vectors of nodes and representation vectors of edges, and the edges representing association relationships between connected nodes; utilizing the graph neural network to generate a transfer matrix based on the characterization vector of the edge, the transfer matrix representing an information transfer mode between connected nodes; determining mutual information between the representation vector of the edge and the transfer matrix; and training the graph neural network by using the mutual information.

Description

technical field [0001] The present disclosure relates to the field of graph neural networks, and in particular to a method for training graph neural networks, graph neural network equipment, devices, and media. Background technique [0002] Graph neural network is a new type of artificial intelligence neural network. Its input is graph structure data, and its output is representation vector, which is used to represent a high-level summary of properties and characteristics. The graph structure data includes representation vectors and edges of nodes. The representation vector of , the edge represents the association relationship between the connected nodes. Through training, the graph neural network can achieve far better results than traditional methods in tasks such as property prediction, classification, and regression. However, the traditional neural network training method does not consider the influence of edge representation vectors on the training results, and ignores...
