| Pseudocode | Yes | Algorithm 1 Reconstruction-based Unsupervised Feature Selection (REFS) |
| Open Source Code | No | The paper does not provide concrete access to source code for the methodology described. |
| Open Datasets | Yes | We choose 8 benchmark datasets of various types for evaluation, including three image datasets, i.e., object image dataset COIL201 [Nene et al., 1996], face image dataset ORL2, handwritten digit datasets USPS [Hull, 1994]; two text datasets, i.e., RELATHE and BASEHOCK3; two microarray datasets, i.e., Lung [Bhattacharjee et al., 2001] and GLIOMA [Nutt et al., 2003] and one spoken letter recognition dataset Isolet4. Footnotes 1, 2, 3, 4 provide URLs for access. |
| Dataset Splits | No | The paper does not provide specific dataset split information (train/validation/test) for reproducing the data partitioning or the clustering experiments. It mentions using K-means for evaluation and varying the number of selected features. |
| Hardware Specification | No | The paper does not provide specific hardware details (e.g., CPU, GPU models, or memory) used for running the experiments. |
| Software Dependencies | No | The paper mentions K-means and Lasso but does not provide specific software dependencies with version numbers. |
| Experiment Setup | Yes | For Lap Score, MCFS, UDFS and FSASL, we specify the number of neighborhood size to be 5 to construct the Laplacian matrix on the data instances following previous work. In REFS, we also set the number nearest neighborhood size p to be 5, but the Laplacian matrix is built on the feature vectors instead of on the data instances. ... tune these regularization parameters for all methods by grid search and report the best performance. |
