Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

| Pseudocode | No | The paper does not contain structured pseudocode or algorithm blocks. |
| Open Source Code | No | The paper does not provide concrete access to source code for the methodology described. |
| Open Datasets | Yes | Finally, we show the similarity of the NC metrics that are obtained for the nonlinear extended UFM in Figure 4 (rather than those in Figure 3) and metrics obtained by a practical well-trained DNN, namely Res Net18 (He et al., 2016) (composed of 4 Res Blocks), trained on MNIST with SGD with learning rate 0.05 (divided by 10 every 40 epochs) and weight decay (L2 regularization) of 5e-4. Figure 5 shows the results for two cases: 1) MSE loss without bias in the FC layer; and 2) the widely-used setting, with cross-entropy loss and bias. (Additional experiments with CIFAR10 dataset appear in Appendix G). |
| Dataset Splits | No | The paper mentions training on MNIST and CIFAR10 but does not specify the train/validation/test dataset splits (e.g., percentages or sample counts). |
| Hardware Specification | No | The paper does not provide specific hardware details (e.g., GPU/CPU models, memory amounts) used for running its experiments. |
| Software Dependencies | No | The paper mentions Res Net18 but does not provide specific software dependencies with version numbers (e.g., library names, framework versions). |
| Experiment Setup | Yes | Figure 1 corroborates Theorem 3.1 for K = 4, d = 20, n = 50 and λW = λH = 0.005 (no bias is used, equivalently λb ). Both W and H are initialized with standard normal distribution and are optimized with plain gradient descent with step-size 0.1. ... trained on MNIST with SGD with learning rate 0.05 (divided by 10 every 40 epochs) and weight decay (L2 regularization) of 5e-4. |
