| Pseudocode | Yes | Algorithm 1: The Surrogate Leverage Weighted RFF Algorithm in KRR |
| Open Source Code | Yes | The source code of our implementation can be found in http://www.lfhsgre.org. |
| Open Datasets | Yes | These datasets can be downloaded from https://www.csie.ntu.edu.tw/ cjlin/libsvmtools/ datasets/ or the UCI Machine Learning Repository2. |
| Dataset Splits | Yes | The regularization parameter λ is tuned via 5-fold inner cross validation over a grid of {0.05, 0.1, 0.5, 1}. |
| Hardware Specification | Yes | All experiments are implemented in MATLAB and carried out on a PC with Intel i5-6500 CPU (3.20 GHz) and 16 GB RAM. |
| Software Dependencies | No | The paper states 'All experiments are implemented in MATLAB', but it does not specify a version number for MATLAB or any other software libraries used, which is required for reproducibility. |
| Experiment Setup | Yes | We choose the popular shift-invariant Gaussian/RBF kernel for experimental validation, i.e., k(x, x ) = exp( x x 2/σ2). Following (Avron et al. 2017), we use a fixed bandwidth σ = 1 in our experiments. The regularization parameter λ is tuned via 5-fold inner cross validation over a grid of {0.05, 0.1, 0.5, 1}. |
