**TLDR:** A GNN architecture designed to strengthen the theoretical power of distinguishing graph structures.

<p>The Graph Isomorphism Network is an important architecture developed to achieve highly discriminative representation learning on graphs. It is especially notable because of its theoretical connection to the Weisfeiler-Lehman test. The goal is to build neighborhood aggregation mechanisms that can distinguish graph structures more precisely. It is a strong example of how theory and practical GNN design can meet.</p>
