A recent paper published in Transactions on Machine Learning Research highlights a theoretical limitation of Message-Passing Graph Neural Networks (GNNs). The research demonstrates that these GNN architectures are fundamentally incapable of handling triangular factorizations, a crucial operation in certain mathematical problems. This finding suggests a potential ceiling for the capabilities of current Message-Passing GNNs in approximating specific complex functions. AI
