Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in [1].

| Pseudocode | No | The paper describes algorithms (e.g., greedy forward selection) but does not present them in a structured pseudocode or algorithm block format. |
| Open Source Code | No | The paper mentions using publicly available implementations for baselines (scikit-learn, Spike and Slab) but does not provide access to its own source code. |
| Open Datasets | Yes | FMRI data were collected from 126 participants while the subjects performed a stop-signal task [24]. ... f MRI data was provided by the Consortium for Neuropsychiatric Phenomics (NIH Roadmap for Medical Research grants UL1-DE019580, RL1MH083269, RL1DA024853, PL1MH083271). |
| Dataset Splits | Yes | For each of these models, the hyperparameter was selected in an inner 5-fold cross validation loop. |
| Hardware Specification | No | The paper does not explicitly specify the hardware (e.g., CPU, GPU models) used for running the experiments. |
| Software Dependencies | No | The paper mentions software like 'scikit-learn python package [20]' and 'publicly available implementation of Spike and Slab [21]' but does not provide specific version numbers for these dependencies. |
| Experiment Setup | Yes | The noise variance hyperparameter for Ridge and ARD were selected from the set 10{ 4, 3,...,4}. Lasso was evaluated using the default scikit-learn implementation where the hyperparameter is selected from 100 logarithmically spaced values based on the maximum correlation between the features and the response. |
