Pseudocode Yes Algorithm 1 The adaptive LADMM algorithm to solve Ck, Gk, Ek, k = 1, ..., K
Open Source Code No The paper does not provide concrete access to source code or explicitly state its release.
Open Datasets Yes Movie Lens. This dataset was downloaded from [12] and contained 100,000 user ratings [...] NCI-DREAM Challenge. The data on the reactions of 46 breast cancer cell lines to 26 drugs and the expression data of 18633 genes for all the cell lines were provided by NCI-DREAM Chal-lenge [10].
Dataset Splits Yes The hyperparameters λ s and the rank of G (required by IMC and Dirty IMC) were tuned via the same cross validation process: we randomly picked 10% of the given entries to form a validation set.
Hardware Specification No The paper does not provide specific hardware details used for running its experiments.
Software Dependencies No The paper mentions algorithms and methods but does not provide specific software dependencies with version numbers.
Experiment Setup Yes The hyperparameters λ s and the rank of G (required by IMC and Dirty IMC) were tuned via the same cross validation process: we randomly picked 10% of the given entries to form a validation set. Then models were obtained by applying each method to the remaining entries with a specific choice of λ from 10 3, 10 2, ..., 104. The average validation RMSE was examined by repeating the above procedure six times. The hyperparameter values that gave the best average validation RMSE were chosen for each method. For IMC and Dirty IMC, the best rank of G was chosen from = 1 to 15 within each data split.
