Pseudocode No The paper describes the algorithms through mathematical formulations and textual explanations but does not include explicit pseudocode or an algorithm block.
Open Source Code Yes The codes are publicly available at https://github.com/Ali Hashemi-ai/Dugh-Neur IPS-2021.
Open Datasets No The paper uses simulated data generated according to described procedures and real MEG/EEG data recordings, but does not provide concrete access information (URL, DOI, repository, or formal citation for public availability) for the specific datasets used in the experiments.
Dataset Splits No The paper does not provide specific details on dataset splits (e.g., training, validation, or test percentages/counts) for reproducibility.
Hardware Specification Yes All experiments are performed using Matlab on a machine with a 2.50 GHz Intel(R) Xeon(R) Platinum 8160 CPU.
Software Dependencies No The paper mentions 'Matlab' but does not specify a version number or other software dependencies with their versions.
Experiment Setup Yes In the first experiment, we compare the reconstruction performance... for a range of SNR levels, numbers of time samples, and orders of AR coefficients. ... P {1, 2, 5, 7}. ... α {0.55, 0.65, 0.7, 0.8}, which correspond to the following SNRs: SNR {1.7, 5.4, 7.4, 12} (d B). ... N0 = 3 active sources. ... T {10, 20, 50, 100}.
