| Pseudocode | No | The paper describes algorithmic steps and mathematical formulations for GRETEL's components and operations but does not present them in clearly labeled 'Pseudocode' or 'Algorithm' blocks. |
| Open Source Code | Yes | Information about the datasets and hyper-parameters are displayed in Table 1, code and datasets are publicly available at https://github.com/jbcdnr/gretel-path-extrapolation. |
| Open Datasets | Yes | Information about the datasets and hyper-parameters are displayed in Table 1, code and datasets are publicly available at https://github.com/jbcdnr/gretel-path-extrapolation. ... We ran an experiment based on a small dataset of food deliveries (229 traces) occurring over the Open Street Map road network of Lausanne (18156 nodes, 32468 edges). ... In the Wikispeedia game [West et al., 2009]... |
| Dataset Splits | No | Table 1 lists 'train/test 80% / 20%' for both GPS and Wikispeedia datasets, but no explicit validation split percentage or methodology is mentioned. |
| Hardware Specification | No | The paper does not provide any specific details about the hardware (e.g., GPU models, CPU types, memory) used to run the experiments. |
| Software Dependencies | No | The paper mentions training parameters like 'Adam learning rate' but does not specify software dependencies (e.g., Python, PyTorch, TensorFlow versions) with specific version numbers. |
| Experiment Setup | Yes | Information about the datasets and hyper-parameters are displayed in Table 1: Adam learning rate 0.01 0.1 batch size 5 10 # epochs 200 5. |
