Pseudocode Yes The complete process is presented in Algorithm (1).
Open Source Code Yes The source codes are available at Git Hub. (...) The Python code associated with GAMTL is available online 1. https://github.com/shgo/gamtl
Open Datasets Yes The ADNI dataset was collected by the Alzheimer s Disease Neuroimaging Initiative (ADNI) and pre-processed by a team from University of California at San Francisco, as described in [Liu et al., 2018]
Dataset Splits Yes For each amount of samples, the parameters of all methods were chosen by crossvalidation using 30% of the training set. (...) Regularization parameters for the methods are chosen by a 5-fold cross-validation procedure using training data.
Hardware Specification No The paper does not provide any specific hardware details used for running the experiments, such as GPU or CPU models.
Software Dependencies No The paper mentions 'The Python code associated with GAMTL is available online' but does not specify version numbers for Python or any libraries used (e.g., PyTorch, TensorFlow, scikit-learn).
Experiment Setup Yes All variants of GAMTL used λ1 [10e 5, , 0.03], λ2 [0.01, , 0.5], and λ3 [0.008, , 0.15]. (...) To account for variability in the data, 30 independent executions were performed.
