Pseudocode Yes Algorithm 1 Hyper Near: Node Inj Ection Attack on Hype Rgraph
Open Source Code Yes Our code is available at https://github.com/ca1man-2022/ Hyper Near.
Open Datasets Yes We evaluate our models on five real-world hypergraph datasets for hypernode classfication tasks, including DBLP (Rossi & Ahmed, 2015), Pubmed, Citeseer and Cora (Sen et al., 2008).
Dataset Splits No The paper mentions using 'the same preprocessed hypergraphs as those provided in the official implementations of Hyper GCN (Yadati et al., 2019) and Uni GNN (Huang & Yang, 2021)', but it does not explicitly provide specific percentages, counts, or a detailed methodology for these dataset splits within the text.
Hardware Specification Yes All experiments are conducted on a device with AMD EPYC 7543 32-core processor and a NVIDIA RTX A6000 GPU with 48 GB of RAM.
Software Dependencies No The paper does not explicitly mention specific software dependencies with version numbers (e.g., Python, PyTorch, TensorFlow, CUDA versions).
Experiment Setup Yes The default hyperparameter settings in our method are as follows, the parameter random seed s is 4202, the choice of hyperedge k is 10%, the ratio of the injected nodes α is 5%, the effect of controlling the loss of homophily λ and τ is 0.1.
