Description This data is the ground truth for the "evaluation dataset" for the DCASE 2020 Challenge Task 2 "Unsupervised Detection of Anomalous Sounds for Machine Condition Monitoring" [task description]. 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 400 samples for each Machine Type and Machine ID used in the evaluation dataset, none of which have any condition label (i.e., normal or anomaly). This ground truth data contains the condition labels. Data format The ground truth data is a CSV file like the following: --------------------------------- fan id_01_00000000.wav,normal_id_01_00000098.wav,0 id_01_00000001.wav,anomaly_id_01_00000064.wav,1 ... id_05_00000456.wav,anomaly_id_05_00000033.wav,1 id_05_00000457.wav,normal_id_05_00000049.wav,0 pump id_01_00000000.wav,anomaly_id_01_00000049.wav,1 id_01_00000001.wav,anomaly_id_01_00000039.wav,1 ... id_05_00000346.wav,anomaly_id_05_00000052.wav,1 id_05_00000347.wav,anomaly_id_05_00000080.wav,1 slider id_01_00000000.wav,anomaly_id_01_00000035.wav,1 id_01_00000001.wav,anomaly_id_01_00000176.wav,1 ... --------------------------------- "Fan", "pump", "slider", etc mean "Machine Type" names. The lines following a Machine Type correspond to pairs of a wave file in the Machine Type and a condition label. The first column shows the name of a wave file. The second column shows the original name of the wave file, but this can be ignored by users. The third column shows the condition label (i.e., 0: normal or 1: anomaly). How to use A system for calculating AUC and pAUC scores for the "evaluation dataset" is available on the Github repository [URL]. The ground truth data is used by this system.
