| Pseudocode | Yes | Algorithm 1 PERCEPTRON@K-AVG, Algorithm 2 PERCEPTRON@K-MAX, Algorithm 3 SGD@K-AVG, Algorithm 4 Subgradient calculation for ℓavg prec@k( ) |
| Open Source Code | No | The paper does not include an unambiguous statement about releasing source code or a direct link to a code repository for the described methodology. |
| Open Datasets | Yes | Datasets: We evaluated our methods on 7 publicly available benchmark datasets: a) PPI, b) KDD Cup 2008, c) Letter, d) Adult, e) IJCNN, f) Covertype, and g) Cod-RNA. |
| Dataset Splits | No | The paper states 'We used 70% of the data for training and the rest for testing.' but does not explicitly mention a separate validation split or its proportion. |
| Hardware Specification | No | The paper does not provide specific hardware details (e.g., exact GPU/CPU models, processor types, or memory amounts) used for running its experiments. |
| Software Dependencies | No | The paper only states 'All methods were implemented in C.' but does not list specific software packages, libraries, or solvers with version numbers required to replicate the experiments. |
| Experiment Setup | Yes | The perceptron and SGD methods were given a maximum of 25 passes over the data with a batch length of 500. |
