Pseudocode No No pseudocode or algorithm blocks were found in the paper.
Open Source Code No The paper does not provide any statement or link indicating that the source code for the described methodology is publicly available.
Open Datasets No We use two real-world datasets, Beijing and Shanghai. ... The paper uses internal datasets ('Beijing and Shanghai') without providing a public link, DOI, repository, or formal citation to access them. They are presented as data collected and used by the authors, not explicitly made available for public access.
Dataset Splits Yes We chronologically order each dataset, set one hour as the unit time step, use the first 60% as the training set, the next 20% as the validation set, and the last 20% for testing.
Hardware Specification Yes All models run on a Linux server with Intel Xeon 5117 CPU, 128 GB Memory, and NVIDIA Tesla P40 GPU.
Software Dependencies No The paper mentions using 'Adam' for optimization and refers to 'XGBoost (Chen and Guestrin 2016)', but it does not provide specific version numbers for these or any other software libraries, programming languages, or environments.
Experiment Setup Yes Specifically, we set the learning rate to 0.0001, hidden dimension d = 512 and α = 0.5. We set input length L = 18 and τ = 3 for prediction. The number of task groups is set to 4. The activation function in GNN is Leaky Re LU with slope ratio 0.1. ... we apply Z-score normalization.
