Pseudocode No The paper describes theoretical derivations and analyses but does not include any pseudocode or algorithm blocks.
Open Source Code No The paper does not provide any specific links or statements regarding the availability of open-source code for the methodology described.
Open Datasets No The paper uses synthetic data generated with specific parameters for simulations, such as 'covariates are Gaussian, xi N(0, Σ)' and '2-scale LJSD (Eq. (10))', rather than referencing publicly available datasets.
Dataset Splits No The paper describes theoretical analysis and simulations based on synthesized data, using terms like 'training error' and 'test error' related to the model's performance on generated data, but it does not specify dataset splits for training, validation, and testing as commonly found in empirical studies.
Hardware Specification No The paper mentions 'Simulations for m = 4000' but does not provide any specific details about the hardware (e.g., GPU/CPU models, memory) used for these computations.
Software Dependencies No The paper mentions 'The NCAlgebra Mathematica package' was used for some derivations, but it does not specify any version numbers for this or any other software dependencies.
Experiment Setup Yes Figure 1: Test error, bias, and variance as a function of the overparameterization ratio (φ/ψ = n1/m) and the alignment θ for the 2-scale LJSD (Eq. (10)) with φ = n0/m = 10/9, σ = tanh, γ = 10 8 and σ2 ε = 1/100. Figure 2: All panels refer to a 3-scale covariance model with α = 103, and ψ = 1/2, s = ρ = 1, γ = 10 13 and σ2 ε = 10.
