Pseudocode Yes Algorithm 1 Loukas Algorithm
Open Source Code Yes The code is available at https://gitlab.inria.fr/anjoly/mp-guarantees-graph-coarsening, and proofs are deferred to App. A.
Open Datasets Yes Node classification on real graphs. We then perform node classification experiments on real-world graphs, namely Cora [35] and Citeseer [15], using the public split from [43].
Dataset Splits Yes Node classification on real graphs. We then perform node classification experiments on real-world graphs, namely Cora [35] and Citeseer [15], using the public split from [43].
Hardware Specification No Additionally, large graphs may be too big to fit on GPUs, and mini-batching graph nodes is known to be a difficult graph sampling problem [14], which may no longer be required on a coarsened graph.
Software Dependencies No The paper mentions 'Code is included as supplementary material, and use only open-source Python libraries' in the NeurIPS checklist, but it does not specify concrete version numbers for any of these libraries or the Python interpreter itself within the main paper or its appendices.
Experiment Setup Yes B.5 Hyper-parameters for Table 1 and Table 2 For all experiments... We apply our adapted version of Loukas coarsening algorithm with ne = 5%N... For SGC cora and SGC Citeseer we make 6 propagations... For GCN Cora and Citeseer we use 2 convolationnal layer with a hidden dimension of 16. For all experiments we use an Adam Optimizer wit a learning rate of 0.05 and a weight decay of 0.01.
