This paper proposes a deep model structure to improve the prediction accuracy of remaining useful life (RUL) of the turbofan engine by using the correlation analysis that reduces the model complexity. The proposed model maximizes the performance by appropriately stacking one dimensional convolutional neural network (1D-CNN), long short-term memory (LSTM), and bidirectional LSTM algorithm. It also includes residual network and dropout technique to improve the learning ability of the proposed model. The result of RUL forecasting using the proposed model is compared with that of various conventional methods, which demonstrates better efficiency yet high performance thanks to excluding the low correlated data.
