**TLDR:** An advanced GNN architecture capable of modeling different node and relation types within the same graph.

<p>Heterogeneous graph neural networks move beyond the assumption that all nodes and edges are of the same type. They can jointly handle different node categories such as users, products, documents, or organizations together with multiple relation types. This makes them far better suited to real-world knowledge graphs and multi-entity systems. However, message passing and representation design become correspondingly more complex.</p>
