# Easy Paper Reproduction for Citation Network (Cora/Pubmed/Citeseer)



This page tries to reproduce all the **Graph Neural Network** paper for Citation Network (Cora/Pubmed/Citeseer), which is the **Hello world**  dataset (**small** and **fast**) for graph neural networks. But it's very hard to achieve very high performance.



All datasets are runned with public split of  **semi-supervised** settings. And we report the averarge accuracy by running 10 times.
