Two stage deep learning for prognostics using multi-loss encoder and convolutional composite features

作者:

Highlights:

• Proposed two-stage deep learning separates feature generation and RUL prediction.

• A multi-loss objective function generates relevant information maximizing features.

• Generated features capture degradation trend with low-noise and low-redundancy.

• Benchmark performance is achieved for C-MAPSS dataset and blade-wear prognostics.

• Analysis of data features reveal the benefits of relevant information maximization.
