| Research Type | Experimental | Empirical results on real-world graphs show that our model outperforms the state-of-the-art competitors. Experiments. We evaluate the superiority of our model with 19 strong competitors on 4 datasets, examine the proposed components by ablation study, and further discuss why Ricci curvature works. |

| Pseudocode | Yes | Algorithm 1: Training CONGREGATE |
| Open Source Code | Yes | Further details and code are provided https://github.com/Curv Cluster/Congregate. |
| Open Datasets | Yes | To evaluate the proposed model, we choose 4 public datasets, i.e., Cora and Citeseer [Devvrit et al., 2022], and larger MAG-CS [Park et al., 2022] and Amazon-Photo [Li et al., 2022]. |
| Dataset Splits | No | The paper does not provide specific percentages or sample counts for training, validation, or test splits. |
| Hardware Specification | No | The paper does not provide specific hardware details such as CPU/GPU models, processor types, or memory amounts used for running experiments. |
| Software Dependencies | No | The paper mentions 'Riemannian Adam [Kochurov et al., 2020]' which implies a PyTorch dependency from the cited work, but it does not explicitly state specific version numbers for software libraries or dependencies. |
| Experiment Setup | Yes | The grid search is performed over search spaces for the hyperparameters, e.g., learning rate: [0.001, 0.003, 0.005, 0.008, 0.01], dropout rate: [0.0, 0.1, 0.2, 0.3, 0.4]. We utilize a 2-layer MLP to approximate the fine-grained curvature. In RGC loss, hyperparameter β of the reweighting is 2 as default. |
