New Recurrent GNNs achieve verifiable symbolic explanations

Researchers have developed a new type of Recurrent Graph Neural Network (GNN) that utilizes set-based aggregation, moving away from traditional multi-set aggregation methods. This advancement allows for verifiable explanations of network behavior directly from their weights, eliminating the need for external halting signals or counting logic. The work establishes a two-directional equivalence between these networks and a specific fragment of the modal mu-calculus, denoted as B$\Sigma^{\circ}_1$, which precisely captures stabilization over finite vocabularies.
