Recurrent Graph Neural Networks: Halting vs. Converging Expressiveness Studied

A new paper explores the expressiveness of different Recurrent Graph Neural Network (RGNN) models, specifically focusing on converging, output-converging, and halting RGNNs. The research establishes that on undirected graphs, converging RGNNs are as expressive as graded-bisimulation-invariant halting RGNNs, while output-converging RGNNs are at least as expressive. The study introduces a "traffic-light" protocol to address the desynchronization challenge when simulating halting RGNNs with converging ones, answering an open question in the field. AI

IMPACT Clarifies theoretical expressiveness limits of RGNN variants, potentially guiding future research in graph-based AI.
