Method and Device for Reducing Computing Operations or Model Components of a GNN

A device for reducing computing operations or model components of a GNN, wherein the device has an evaluation and computation device configured to perform the following:

• providing a GNN architecture in which distances and/or relative orientations between nodes are modeled and processed in the form of edge features;
• providing discretization values of distances and/or relative orientations between nodes of a network graph of the GNN;
• encoding the discretization values into a latent space by an edge-feature encoder;
• performing retrievable and index-based storage of the encoded discretization values in a database;
• and
• retrieving the encoded discretization values from the database by the GNN based on indices used by the GNN to reduce the computing operations or model components associated with the encoded discretization values.
