Pseudocode Yes Algorithm 1 Trimmed Graphical Lasso in (3)
Open Source Code No The paper mentions using 'R implementations provided by the methods authors' for comparison methods and refers to supplementary material for proofs, but does not provide concrete access to its own source code.
Open Datasets Yes We analyze a yeast microarray dataset generated by [28].
Dataset Splits Yes We use 5-fold-CV to choose the tuning parameters for each method.
Hardware Specification Yes Experiments were run on R in a single computing node with a Intel Core i5 2.5GHz CPU and 8G memory.
Software Dependencies No The paper mentions 'R' and various R packages (t-lasso, t*-lasso, robust LL, glassopath) used for the experiments but does not provide specific version numbers for any of them.
Experiment Setup Yes For the robust-LL method we set β = 0.05 and for trimglasso we use h/n = 80%. We use 5-fold-CV to choose the tuning parameters for each method.
