Description This data is the ground truth for the "evaluation dataset" for the DCASE 2021 Challenge Task 2 "Unsupervised Anomalous Sound Detection for Machine Condition Monitoring under Domain Shifted Conditions". In the task, three datasets have been released: "development dataset", "additional training dataset", and "evaluation dataset". The evaluation dataset was the last of the three released and includes around 200 samples for each machine type, section index, and domain, none of which have a condition label (i.e., normal or anomaly). This ground truth dataset contains the condition labels. Data format The CSV file for each machine type, section index, and domain includes the ground truth data like the following: --------------------------------- section_03_source_test_0000.wav,1 section_03_source_test_0001.wav,1 ... section_03_source_test_0198.wav,0 section_03_source_test_0199.wav,1 --------------------------------- The first column shows the name of a wave file. The second column shows the condition label (i.e., 0: normal or 1: anomaly). How to use A script for calculating the AUC, pAUC, precision, recall, and F1 scores for the "evaluation dataset" is available on the Github repository [URL]. The ground truth data are used by this system. For more information, please see the Github repository.
