Learning to Adapt to Domain Shifts with Few-shot Samples in Anomalous Sound Detection [article]

Bingqing Chen, Luca Bondi, Samarjit Das
2022 arXiv   pre-print
We define multiple auxiliary classification tasks based on meta-information and leverage gradient-based meta-learning to improve generalization to different shifts.  ...  Grounded in the application of machine health monitoring, we propose a framework that adapts to new conditions with few-shot samples.  ...  INTRODUCTION Anomaly detection is the task of identifying anomalous observations [1] - [5] . In this paper, we focus on anomaly detection applied to machine health monitoring via audio signal.  ...
