Pseudocode No The paper describes the proposed algorithm in text and mathematical formulas but does not include any structured pseudocode or algorithm blocks.
Open Source Code Yes The code and Nosaic MNIST are publicly available at https://github.com/Taiki Miyagawa/SPRT-TANDEM.
Open Datasets Yes Evaluated public databases are NMNIST, UCF, and Si W. ... The code and Nosaic MNIST are publicly available at https://github.com/Taiki Miyagawa/SPRT-TANDEM. ... UCF101 action recognition database (Soomro et al., 2012) and Spoofing in the Wild (Si W) database (Liu et al., 2018).
Dataset Splits Yes Training, validation, and test datasets are split and fixed throughout the experiment. ... The training, validation, and test datasets contain 50,000, 10,000, and 10,000 videos with frames of size 28 28 1 (gray scale).
Hardware Specification Yes All the experiments are conducted with custom python scripts running on NVIDIA Ge Force RTX 2080 Ti, GTX 1080 Ti, or GTX 1080 graphics card.
Software Dependencies Yes We use Tensorflow 2.0.0 (Abadi et al. (2015)) as a machine learning framework except when running baseline algorithms that are implemented with Py Torch (Paszke et al. (2019)).
Experiment Setup Yes Hyperparameters of all the models are optimized with Optuna unless otherwise noted so that no models are disadvantaged by choice of hyperparameters. See Appendix H for the search spaces and fixed final parameters.
