Pseudocode Yes The procedure of blockwise masking is summarized in Algorithm 1 in Appendix.
Open Source Code Yes Code will be publicly available at https://github.com/xcyao00/PMAD.
Open Datasets Yes We evaluate the proposed approach on two widely used industrial anomaly detection datasets: the MVTec AD (Bergmann et al. 2019a) and BTAD (Mishra et al. 2021).
Dataset Splits No The paper describes training and testing sets (e.g., '3629 images for training and 1725 images for testing' for MVTec AD), but does not explicitly mention a separate validation set or its split details.
Hardware Specification No The paper does not provide specific hardware details such as GPU/CPU models, memory specifications, or cloud computing resources used for running the experiments.
Software Dependencies No The paper does not list specific software dependencies with version numbers (e.g., 'PyTorch 1.9', 'Python 3.8') needed to replicate the experiment.
Experiment Setup Yes We mainly follow the hyperparameters in (Bao, Dong, and Wei. 2021) to train the reconstruction model. All training hyperparameters are listed in Appendix. Because the sizes of anomalies in different classes are generally different, the same mask ratio for all classes cannot achieve the optimal results. We select a suitable mask ratio for each class through extensive experiments (see Appendix for details).
