| Pseudocode | No | No pseudocode or algorithm blocks were found in the paper. |
| Open Source Code | No | We used the GNN library at https://github.com/alelab-upenn/graph-neural-networks |
| Open Datasets | No | The dataset is generated according to the mobility model in (95) and (96). The dataset consists of 500 time-varying graph signals {Xm}500 m=1 that are calculated under optimal centralized policies {U m}500 m=1. |
| Dataset Splits | Yes | We split the data into 460 examples for training, 20 for validation and 20 for testing. |
| Hardware Specification | No | No specific hardware details (e.g., GPU/CPU models, memory amounts) used for running experiments were mentioned in the paper. |
| Software Dependencies | No | We used the GNN library at https://github.com/alelab-upenn/graph-neural-networks |
| Experiment Setup | Yes | We train a 2-layer ST-GNN on the training data and optimize the mean squared loss using ADAM algorithm with learning rate 0.01 and decaying factors β1 = 0.9 and β2 = 0.999.
