PGL Examples for GCN with StaticGraphWrapper¶
Graph Convolutional Network (GCN) is a powerful neural network designed for machine learning on graphs. Based on PGL, we reproduce GCN algorithms and reach the same level of indicators as the paper in citation network benchmarks.
However, different from the reproduction in examples/gcn, we use pgl.graph_wrapper.StaticGraphWrapper
to preload the graph data into gpu or cpu memories which achieves better performance on speed.
Datasets¶
The datasets contain three citation networks: CORA, PUBMED, CITESEER. The details for these three datasets can be found in the paper.
Dependencies¶
paddlepaddle>=1.6
pgl
Performance¶
We train our models for 200 epochs and report the accuracy on the test dataset.
