Pseudocode Yes Algorithm 1: HTML
Open Source Code Yes Our code is available at https://github.com/jyf123/HTML.
Open Datasets Yes For the unsupervised learning task, we conduct experiments on eight regular-sized graphs, I.e., TUDataset (Morris et al. 2020), and one large-scale graph, i.e., Amazon Photo dataset, which has 7,650 nodes and 119,081 edges. For the transfer learning task, we pre-train our model on ZINC-2M (Sterling and Irwin 2015) and finetune it on eight biochemical molecule datasets.
Dataset Splits No The paper lists datasets used but does not provide specific dataset split information (exact percentages, sample counts, citations to predefined splits, or detailed splitting methodology) needed to reproduce the data partitioning for its experiments.
Hardware Specification No The paper does not provide specific hardware details (exact GPU/CPU models, processor types with speeds, memory amounts, or detailed computer specifications) used for running its experiments.
Software Dependencies No The paper does not provide specific ancillary software details, such as library or solver names with version numbers, needed to replicate the experiment.
Experiment Setup Yes Hyper-parameter experiment. Appropriate adjustment of the introduction of hierarchical topology isomorphism expertise can better improve the model performance, so we conduct hyperparametric experiments on the PROTEINS dataset for α and β, and the results are shown in Figure 6. α and β are range from {1, 1 × 10−1, 1 × 10−2, 1 × 10−3, 1 × 10−4}.
