Pseudocode Yes Algorithm 1 Unsupervised Personalized Feature Selection
Open Source Code No The paper does not provide any concrete access information (e.g., specific repository link, explicit code release statement) for its source code.
Open Datasets Yes We choose 9 datasets from various domains, including (1) four text datasets: CNNStory, Blog Catalog, Flickr and DBLP; (2) two image datasets: Yale and warp PIE10P; (3) three biology datasets: Carcinoma, Prostate GE and TOX171. Detailed statistics of the used datasets are shown in Table 1.
Dataset Splits No The paper does not explicitly provide specific training/validation/test dataset splits by percentage or sample counts.
Hardware Specification No The paper does not provide specific hardware details (e.g., exact GPU/CPU models, memory amounts, or detailed computer specifications) used for running its experiments.
Software Dependencies No The paper does not provide specific ancillary software details with version numbers (e.g., library or solver names with version numbers) needed to replicate the experiment.
Experiment Setup Yes In Laplacian Score, MCFS, NDFS, FSASL and UPFS, we specify the number of nearest neighbors k as 5. It is still an open question to decide the optimal number of selected features in feature selection research. Thus, we set the number of selected features among {10, 20, ..., 300} and report the best clustering results. To study how its variation affects the feature selection performance, we fix two parameters each time and vary the third one in the range of {0.001, 0.01, 1, 10, 100, 1000}.
