Pseudocode Yes We highlight two techniques: random-walk Metropolis-Hastings (MH) and slice sampling. [...] See Alg. 1 of the Supplement. [...] See Alg. 2 of the Supplement. [...] We show this procedure in Alg. 3 of the Supplement.
Open Source Code No The paper does not provide any explicit statements or links indicating that the source code for the described methodology is publicly available.
Open Datasets No The paper uses simulated data and refers to datasets from previous studies or standard feature sets (Waller et al., 2011; Kulesza & Taskar, 2011a; Lowe, 1999; Vedaldi & Fulkerson, 2010; Oliva & Torralba, 2006) but does not provide concrete access information, such as a direct link, DOI, or repository for a publicly available dataset.
Dataset Splits No The paper does not provide specific details on dataset splits (e.g., exact percentages or sample counts for training, validation, and testing sets) or explicit cross-validation setup details beyond mentioning a 'leave-one-out classification' strategy in one application.
Hardware Specification No The paper does not provide any specific hardware details such as GPU or CPU models, memory, or cloud computing instance types used for running the experiments.
Software Dependencies No The paper mentions general software components like 'Python', 'PyTorch', 'CUDA', 'scikit-learn', 'VLFeat', but does not provide specific version numbers for these or other software dependencies.
Experiment Setup Yes The hyperparameters of f(ˆΘ|Θi) tune the width of the distribution, determining the average step size. [...] We test our Bayesian learning algorithms on simulated data generated from a 2-dimensional isotropic kernel (σd = σ, ρd = ρ for d = 1, 2) using Gibbs sampling (Affandi et al., 2013a). We then learn the parameters under weakly informative inverse gamma priors on σ, ρ and α. Details are in the Supplement. [...] We place weakly informative inverse gamma priors on (α, ρ, σ), as specified in the Supplement, and learn the parameters using slice sampling with eigenvalue bounds as outlined in Sec. 3.3.
