An Improved Similarity Matching Bidirectional Gated Recurrent Unit Autoencoder Scheme for Remaining Useful Life Prediction

Remaining useful life (RUL) prediction is an important task of prognostic and health management (PHM), which can ensure the safe and reliable operation of the degradation system. In the previous similarity matching prediction methods, the similarity measure is calculated based on the Euclidean distance at the same time point. This single calculation method ignores the shape similarity of the healt...
