Bag Graph: Multiple Instance Learning using Bayesian Graph Neural Networks

1 code implementation22 Feb 2022 Soumyasundar Pal, Antonios Valkanas, Florence Regol, Mark Coates

Since a meaningful graph representing dependencies between bags is rarely available, we propose to use a Bayesian GNN framework that can generate a likely graph structure for scenarios where there is uncertainty in the graph or when no graph is available.
