| Pseudocode | Yes | Algorithm 1 Subsampling MPE (Su MPE) |
| Open Source Code | Yes | The implementation is available at https://github.com/allan-z/Su MPE. |
| Open Datasets | Yes | We ran our algorithm on nuclear, synthetic and some benchmark datasets taken from the UCI machine learning repository and MNIST, corresponding to all three scenarios described in Sec. 4.2. |
| Dataset Splits | No | The paper describes how samples are drawn for the mixture proportion estimation problem (e.g., m = n = 50,000 instances), and how some benchmark datasets are adapted. However, it does not explicitly provide details about standard train/validation/test dataset splits (e.g., percentages, exact counts, or specific split files) typically used for model training and evaluation. |
| Hardware Specification | No | The paper does not provide any specific details about the hardware used to run the experiments, such as GPU models, CPU types, or memory specifications. |
| Software Dependencies | No | The paper mentions training neural networks and using the MCNP radiation transport code, but it does not specify any software dependencies with version numbers (e.g., 'Python 3.8, PyTorch 1.9'). |
| Experiment Setup | Yes | A 1 hidden layer neural network with 16 neurons was trained to predict P sr(Y = 1|X = x) for x ( , 2], thus A = ( , 2] and α(x) was chosen according to Eqn. (10). |
