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 [1].

| Research Type | Experimental | We experimentally evaluate MAF on a wide range of datasets, and we demonstrate that (a) MAF outperforms Real NVP on general-purpose density estimation, and (b) a conditional version of MAF achieves close to state-of-the-art performance on conditional image modelling even with a general-purpose architecture. |

| Pseudocode | No | The paper describes algorithms and transformations using mathematical equations and descriptive text, but does not include explicit pseudocode or algorithm blocks. |
| Open Source Code | Yes | Code for reproducing our experiments (which uses Theano [29]) can be found at https://github.com/gpapamak/maf. |
| Open Datasets | Yes | Following Uria et al. [32], we perform unconditional density estimation on four UCI datasets (POWER, GAS, HEPMASS, MINIBOONE) and on a dataset of natural image patches (BSDS300). ... For conditional density estimation, we used the MNIST dataset of handwritten digits [17] and the CIFAR-10 dataset of natural images [14]. |
| Dataset Splits | Yes | Each model was trained with early stopping until no improvement occurred for 30 consecutive epochs on the validation set. For each model, we selected the number of hidden layers and number of hidden units based on validation performance |
| Hardware Specification | No | The paper mentions "parallel computing architectures such as Graphics Processing Units (GPUs)" but does not specify any particular GPU models or other hardware details used for the experiments. |
| Software Dependencies | No | The paper mentions using "Theano [29]" but does not specify its version number or any other software dependencies with their versions. |
| Experiment Setup | Yes | All models were trained with the Adam optimizer [11], using a minibatch size of 100, and a step size of 10 3 for MADE and MADE Mo G, and of 10 4 for Real NVP and MAF. A small amount of โ2 regularization was added, with coef๏ฌcient 10 6. |
