MIMII DG: Sound Dataset for Malfunctioning Industrial Machine Investigation for Domain Generalization Task

Description

This dataset is a sound dataset for malfunctioning industrial machine investigation and inspection for domain generalization task (MIMII DG). The dataset consists of normal and abnormal operating sounds of five different types of industrial machines, i.e., fans, gearboxes, bearing, slide rails, and valves. The data for each machine type includes three subsets called "sections", and each section roughly corresponds to a type of domain shift. This dataset is a subset of the dataset for DCASE 2022 Challenge Task 2, so the dataset is entirely the same as data included in the development dataset. For more information, please see the pages of the development dataset and the task description for DCASE 2022 Challenge Task 2.

Baseline system

Two simple baseline systems are available on the Github repositories autoencoder-based baseline and MobileNetV2-based baseline. The baseline systems provide a simple entry-level approach that gives a reasonable performance in the dataset. They are good starting points, especially for entry-level researchers who want to get familiar with the anomalous-sound-detection task.
