> So this is for quickly training different architectures for the same task? It's for instantly training/pretraining any architecture for one or more predefined tasks (e.g., you could have a GNN for visual tasks, a GNN for NLP tasks, etc.), but you could also have a multi-domain GNN which accepts two inputs: an architecture and a domain.
