| Pseudocode | Yes | Algorithm 1 POCSS Algorithm; Algorithm 2 Evaluation Subprocedure |
| Open Source Code | No | The paper does not provide any statement about making the source code available or a link to a code repository. |
| Open Datasets | Yes | The data sets are downloaded from http://archive.ics.uci.edu/ ml/ and http://www.csie.ntu.edu.cn/ cjlin/libsvmtools/datasets/. |
| Dataset Splits | No | The paper uses '10 real-world data sets' and compares algorithms, but does not explicitly state how these datasets were split into training, validation, or test sets. |
| Hardware Specification | No | The paper does not specify any hardware details such as CPU or GPU models used for the experiments. |
| Software Dependencies | No | The paper does not list any specific software dependencies with version numbers. |
| Experiment Setup | Yes | For Two-stage, 2k columns are selected in the randomized stage. For WA , we implement its best version WA -b and set the parameter ϵ = 0.5. For POCSS, the number of iterations is ekn(n + 1) as suggested by Theorem 1. To improve its efficiency, submatrices with at least 2k columns are excluded in the running process, thus the number of iterations is set to 2ek2n. |
