Pseudocode No The paper does not contain any pseudocode or clearly labeled algorithm blocks.
Open Source Code Yes 1https://github.com/cspjiao/CNESE
Open Datasets Yes We conduct the role-based node classification experiments on Air-traffic networks (USA, Brazil, and Europe) [Ribeiro et al., 2017], Actor co-occurrence network [Ma et al., 2019], Reality phone call network [Guo et al., 2020], and Enron email network [Klimt and Yang, 2004].
Dataset Splits No The paper specifies a 70% training set and the rest as test set, but does not explicitly mention a separate validation split or its details.
Hardware Specification No The paper does not provide specific details about the hardware used for running the experiments (e.g., GPU/CPU models, memory).
Software Dependencies No The paper mentions 'Adam SGD optimizer' but does not specify version numbers for any software dependencies or libraries (e.g., Python, PyTorch, TensorFlow).
Experiment Setup Yes The bin number of curvature histograms is set to 80. The width of MLPs and embedding dimension are set to 64. We apply Adam SGD optimizer [Kingma and Ba, 2015] with learning rate 0.001 and batch size 32 for at most 50 epochs. L2 regularization with weight 0.001 is adopted to avoid overfitting. In later experiments, unless otherwise stated, parameter α of α-Ricci-curvature is set as 0.05, and 0.5 on Brazil and the other datasets respectively. β is set to 5 and γ is set to and 2.
