Vol. 33, pp. Based on this, we propose a generalization of GNNs, so-called $k$-dimensional GNNs ($k$-GNNs), which can take higher-order graph structures at multiple scales into account. These higher-order structures play an essential role in the characterization of social networks and molecule graphs. Gori et al. However, graphs alone cannot capture the multi-level … In AAAI, 2019. In recent years, graph neural networks (GNNs) have emerged as a powerful neural architecture to learn vector representations of nodes and graphs in a supervised, end-to-end fashion.

Proc. [2] C. Morris et al. Hence, it accounts for the higher-order interactions between vertices. Various recent proposals increase the distinguishing power of Graph Neural Networks GNNs by propagating features between -tuples of vertices.The distinguishing power of these "higher-order'' GNNs is known to be bounded by the -dimensional Weisfeiler-Leman (WL) test, yet their memory requirements limit their applicability. Graph neural networks (GNNs) have recently achieved great successes in a wide variety of applications, such as chemistry, reinforcement learning, knowledge graphs, traffic networks, or computer vision. Ryan L Murphy, Balasubramaniam Srinivasan, Vinayak Rao, and Bruno Ribeiro. AAAI. Weisfeiler and Leman Go Neural: Higher-order Graph Neural Networks. In contrast to current graph neural networks which follow a simple neighborhood aggregation scheme, our DNA procedure allows for a selective and node-adaptive aggregation of neighboring embeddings of potentially differing locality. Training deep graph neural networks is hard. It is known (Xu et al., 2019) that GNN variants such as GCNs (Kipf and Welling, 2017) and GraphSAGE (Hamilton et al., 2017) are no more discriminative than the Weisfeiler-Leman (WL) test.

(2017) showed that common graph neural net models mod-els may be studied as Message Passing Neural Networks (MPNNs). It has recently been shown that the expressiveness of GNNs can be characterised precisely by the combinatorial Weisfeiler-Leman algorithms and by finite variable counting logics. : How Powerful are Graph Neural Networks?
