Pseudocode No The paper does not contain structured pseudocode or algorithm blocks.
Open Source Code No The paper does not provide concrete access to source code for the methodology described.
Open Datasets Yes The dataset is available in ftp://msel.mayo.edu/EEG_Data/ and The crime data are available on http://opendata.dc.gov
Dataset Splits Yes We use 10-fold cross-validation (CV) to evaluate predictions with 30% test set while keeping the same proportion of SOZ and non-SOZ observations in both sets.
Hardware Specification No The paper does not provide specific hardware details used for running its experiments.
Software Dependencies No The paper does not provide specific ancillary software details with version numbers.
Experiment Setup Yes For each observation, we simulate 3 chains of 7000 Gibbs iterations, and discard the first 3000 as burn-in phase. Each sampling chain is initialized with parameters sampled from their priors. We set Γ(a, b) prior on the ARD precisions as a = |Sk| and b = a/1000, where Sk is defined in (23).
