Pseudocode Yes Algorithm 1 Solving eqn. (5) via CG; Algorithm 2 Infeasible IPM
Open Source Code No The paper does not provide concrete access to source code for the methodology described. It does not include a link to a repository or explicitly state that the code is released.
Open Datasets Yes We demonstrate the empirical performance of our algorithm on a variety of synthetic and real-world datasets from the UCI ML Repository [20], such as ARCENE, DEXTER [23], Driv Face [16], and a gene expression cancer RNA-Sequencing dataset that is part of the PANCAN dataset [50].
Dataset Splits No The paper references datasets and their use in experiments but does not explicitly provide specific dataset split information (percentages, sample counts, or citations to predefined splits) for training, validation, and testing needed to reproduce the data partitioning. It mentions 'binary classification' and 'number of training points' but no clear splits.
Hardware Specification Yes The experiments were implemented in Python and run on a server with Intel E52623V3@3.0GHz 8 cores and 64GB RAM.
Software Dependencies No The paper states, "The experiments were implemented in Python" but does not specify version numbers for Python or any key libraries, solvers, or other software components used.
Experiment Setup Yes If not specified: τ = 10 9, tol CG = 10 5, and σ = 0.5. We evaluated a Gaussian sketching matrix and the initial triplet (x, y, s) for all IPM algorithms was set to be all ones.
