| Pseudocode | No | The paper does not contain any sections or figures explicitly labeled as "Pseudocode" or "Algorithm". |
| Open Source Code | Yes | We release improved versions of t SNE, UMAP, and GDR that are fully plug-andplay with the traditional libraries. |
| Open Datasets | Yes | The paper uses well-known public datasets such as MNIST [Deng, 2012], Fashion MNIST [Xiao et al., 2017], Coil-100 [NENE, 1996], Single Cell [Tasic et al., 2018], and Cifar-10 [Krizhevsky, 2009]. |
| Dataset Splits | No | The paper mentions "training" and metrics like "k NN accuracy" and "V-measure" but does not specify train/validation/test splits, percentages, or absolute sample counts for data partitioning. |
| Hardware Specification | No | The paper mentions running computations "on a GPU" but does not specify any particular GPU model (e.g., NVIDIA A100), CPU model, or other detailed hardware specifications. |
| Software Dependencies | No | The paper mentions |
| Experiment Setup | Yes | The paper discusses various aspects of the experimental setup, including hyperparameter effects (Table 1, Table 4), learning rate adjustments ("t SNE s learning rate stays constant over training while UMAP s linearly decreases"), and default settings for GDR ("GDR therefore defaults to t SNE s asymmetric attraction and a and b scalars along with UMAP s distance-metric, initialization, nearest neighbors, and pij symmetrization"). |
