Frequently asked questions

What security considerations are important when working with graph neural networks?

Security considerations include Personally Identifiable Information (PII), graph attacks, audits, and logging.

How can I integrate graph databases, feature stores, and model registries into my GNN workflow?

Integration involves utilizing graph databases for data storage, feature stores for managing features, and model registries for tracking models.

What monitoring strategies should be employed to detect drift or changes in the graph structure?

Monitoring strategies involve tracking graph structure drift, setting alerts for significant changes, and implementing regular audits.
