Higher-order Clustering and Pooling for Graph Neural Networks

1 code implementation2 Sep 2022 Alexandre Duval, Fragkiskos Malliaros

Graph Neural Networks achieve state-of-the-art performance on a plethora of graph classification tasks, especially due to pooling operators, which aggregate learned node embeddings hierarchically into a final graph representation.

Graph Classification

Fusing Document, Collection and Label Graph-based Representations with Word Embeddings for Text Classification
