ToyADMOS2
收藏资源简介:
ToyADMOS2是一个用于机器操作声音异常检测的大规模数据集,专门设计来评估系统在域转移条件下的性能。该数据集包含两个子数据集,用于机器状态检查:具有固定几何任务的机器故障诊断和具有移动任务的机器故障诊断。通过引入操作条件的几种差异来表示域转移,例如使用相同类型的机器但具有不同的机器模型和部件配置、不同的操作速度、麦克风布置等。每个子数据集包含超过27,000个正常机器操作声音样本和超过8,000个异常声音样本,记录时使用五到八个麦克风。
ToyADMOS2 is a large-scale dataset for machine operating sound anomaly detection, specifically designed to evaluate system performance under domain shift conditions. This dataset includes two subsets for machine condition monitoring: machine fault diagnosis with fixed-geometry tasks and machine fault diagnosis with mobile tasks. Several variations of operating conditions are introduced to represent domain shift, such as using machines of the same type but with different machine models and component configurations, varying operating speeds, microphone placements, and so on. Each subset contains over 27,000 normal machine operating sound samples and over 8,000 anomalous sound samples, recorded using 5 to 8 microphones.
