Pseudocode No The paper describes the methodology in text and mathematical formulas, but does not include a clearly labeled pseudocode or algorithm block.
Open Source Code Yes Code https://github.com/caoji2001/HOSER
Open Datasets No We assess the performance of HOSER and other baselines using three trajectory datasets from Beijing, Porto, and San Francisco. Each dataset is randomly split into training, validation, and test sets in a 7:1:2 ratio. Further dataset details are provided in Appendix B.1.
Dataset Splits Yes Each dataset is randomly split into training, validation, and test sets in a 7:1:2 ratio.
Hardware Specification Yes All experiments are conducted on a single NVIDIA RTX A6000 GPU.
Software Dependencies No The paper does not explicitly state specific software dependencies with version numbers.
Experiment Setup No The paper describes the model architecture and loss functions, but does not provide specific hyperparameter values (e.g., learning rate, batch size, number of epochs) or optimizer settings in the main text.
