Accurate remaining useful life (RUL) predictions are crucial for safe operation of aero-engines.
This paper introduces a multi-granularity supervised contrastive (MGSC) framework to address limitations in current RUL prediction methods.
The MGSC framework aims to align samples with the same RUL label in the feature space, improving prediction accuracy.
The proposed strategy is implemented on the CMPASS dataset and enhances RUL prediction accuracy using a convolutional long short-term memory network as a baseline.
