Description
This dataset is 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". This evaluation dataset was the last of the three released. This dataset includes around 400 samples for each Machine Type and Machine ID used in the evaluation dataset, none of which have a condition label (i.e., normal or anomaly).
The recording procedure and data format are the same as the development dataset and additional training dataset. The Machine IDs in this dataset are the same as those in the additional training dataset. For more information, please see the pages of the development dataset and the task description.
After the DCASE 2020 Challenge, we released the ground truth for this evaluation dataset.
Directory structure
Once you unzip the downloaded files from Zenodo, you can see the following directory structure. Machine Type information is given by directory name, and Machine ID and condition information are given by file name, as:
/eval_data
/ToyCar
/test (Normal and anomaly data for all Machine IDs are included, but they do not have a condition label.)
/id_05_00000000.wav
...
/id_05_00000514.wav
/id_06_00000000.wav
...
/id_07_00000514.wav
/ToyConveyor (The other Machine Types have the same directory structure as ToyCar.)
/fan
/pump
/slider
/valve
The paths of audio files are:
"/eval_data//test/id__[0-9]+.wav"
For example, the Machine Type and Machine ID of "/ToyCar/test/id_05_00000000.wav" are "ToyCar" and "05", respectively. Unlike the development dataset and additional training dataset, its condition label is hidden.
Baseline system
A simple baseline system is available on the Github repository [URL]. The baseline system provides a simple entry-level approach that gives a reasonable performance in the dataset of Task 2. It is a good starting point, especially for entry-level researchers who want to get familiar with the anomalous-sound-detection task.
