This paper proposes a novel RUL prediction model named AA-LSTM. We use a Bi-LSTM-based autoencoder to extract degradation information contained in the time series data. Meanwhile, a generative adversarial network is used to assist the autoencoder in extracting abstract representation, and then a ...

Finally, we can create a composite LSTM Autoencoder that has a single encoder and two decoders, one for reconstruction and one for prediction. We can implement this multi-output model in Keras using the functional API. You can learn more about the functional API in this post: How to Use ...

For the autoencoder, the entropy function reduces into:(4)LHx,z=-∑k=1Nxklogzk+1-xklog1-zk Apart from using the traditional autoencoder, a special type of convolution branch is introduced for classification purpose. In this CNN-based block, in place of using conventional CNN, depthwise se...
A deep learning framework for financial time series using stacked autoencoders and long short term memory The application of deep learning approaches to finance has received a great deal of attention from both investors and researchers. This study presents a novel deep learning framework where wavelet...

If we are extracting more than 1 last examples, we have to average their prediction results. The second scaler halps us do just that. """ max_num_test_batches = np.int(np.floor((len(test_data_for_an_engine) - window_length)/shift)) + 1 if max_num_test_batches < num_test_...
The first difference concerns the objective of the prediction task of Schmidhuber’s model, which is predicting the next input from the previous inputs. In contrast, the LSTM-SAE model tries to reconstruct the inputs by establishing the LSTM autoencoder. Nevertheless, the major difference lies ...
