Pseudocode No The paper refers to extended algorithms and details in the supplemental document (e.g., Section E.1 and E.2), but no pseudocode or algorithm blocks are present in the main text.
Open Source Code No The paper does not provide an explicit statement or link indicating that the source code for the proposed method is openly available.
Open Datasets Yes Coat Shopping Dataset, which is available at http://www.cs.cornell.edu/ schnabts/mnar/. ... Yahoo! Webscope Dataset, which is available at http://research.yahoo.com/AcademicRelations.
Dataset Splits Yes For all methods mentioned above, we randomly separate 20% of the observed entries in every simulated dataset and use it as the validation set to select tuning parameters. (Section 6) and For both datasets, we separate half of the test data set as the validation set to select tuning parameters for all methods. (Section 7)
Hardware Specification No Portions of this research were conducted with high performance research computing resources provided by Texas A&M University (https://hprc.tamu.edu). This statement is too general and does not provide specific hardware details like GPU/CPU models or memory.
Software Dependencies No The paper mentions various algorithms and methods (e.g., 'L-BFGS-B algorithm', 'Soft Impute') but does not specify any software names with version numbers for implementation or experimental setup.
Experiment Setup No The paper describes dataset generation, noise settings, and missing mechanisms, and mentions tuning parameter selection via a validation set, but it does not provide concrete hyperparameter values (e.g., learning rate, batch size, epochs) or detailed optimizer settings for the models.
