DA-VICReg: a data augmentation-free self-supervised learning approach for diesel engine fault diagnosis

Tianyou Chen,
Yang Xiang,
Jiaxing Wang

Abstract: Self-supervised learning aims to extract useful representations from unlabeled data by maximizing the agreement between positive pairs. However, traditional self-supervised learning relies on carefully designed data augmentation methods to generate positive pairs. When dealing with 1D vibration signals, data augmentation prone to potentially compromise the fault information in the original signals. Therefore, this paper proposes a data augmentation-free self-supervised learning framework for diesel engine faul… Show more
