| Pseudocode | No | The paper describes algorithms but does not provide a formal pseudocode block or algorithm listing. |
| Open Source Code | Yes | We also provide open-source implementation for our descriptor and for the other approaches [CFK+19, Vip20], in a public Python package [Car20]. |
| Open Datasets | Yes | We use time series data sets from the UCR archive [DBK+18] with moderate sizes and lengths; this ensures that the kernel matrices obtained with Multiparameter Persistence Kernel have reasonable sizes and that the point clouds obtained with the Takens embedding in R3 have a reasonable number of points. |
| Dataset Splits | Yes | Moreover, we use the train/test split that is suggested for each data set. Resolutions for Multiparameter Persistence Landscapes and Images are 5-fold cross-validated over the set of values {10, 50}, and the powers and bandwidths of the Multiparameter Persistence Images and Kernels are also 5-fold cross-validated with values in {0, 1} (power) and 10{ 2, 1,0,1,2} (bandwidth). |
| Hardware Specification | Yes | All experiments have been run on an AWS machine with a Xeon Platinum 8175 processor. |
| Software Dependencies | No | The paper mentions a "public Python package" but does not list specific software dependencies with version numbers (e.g., Python version, library versions). |
| Experiment Setup | Yes | Resolutions for Multiparameter Persistence Landscapes and Images are 5-fold cross-validated over the set of values {10, 50}, and the powers and bandwidths of the Multiparameter Persistence Images and Kernels are also 5-fold cross-validated with values in {0, 1} (power) and 10{ 2, 1,0,1,2} (bandwidth). |
