Pseudocode Yes Algorithm 1: Accelerated proximal gradient algorithm for SLOPE (3)
Open Source Code No The paper does not provide an unambiguous statement or a direct link to a source-code repository for the methodology described.
Open Datasets No The paper primarily uses simulated data, and does not provide concrete access information (specific link, DOI, repository name, formal citation with authors/year, or reference to established benchmark datasets) for a publicly available or open dataset.
Dataset Splits No The paper uses simulated data and describes the generation process, but it does not provide specific dataset split information (exact percentages, sample counts, citations to predefined splits, or detailed splitting methodology) for training, validation, and testing needed to reproduce the data partitioning of a fixed dataset.
Hardware Specification Yes All experiments are implemented in Python on a Macbook Pro with Apple M1 and 16 GB memory.
Software Dependencies No The paper mentions 'implemented in Python' but does not provide specific ancillary software details like library names with version numbers (e.g., Python 3.8, PyTorch 1.9).
Experiment Setup Yes The number of relevant features t is set to vary within {50, 100, 200, 300, 400, 500} and the nonzero regression coefficients are equal to 3 2 log n. We set the target FDR level α = 0.1 and γ = 0.1 for F-SLOPE, and set k = {5, 10, 15, 20, 25, 30} and α = 0.1 for k-SLOPE.
