Coming back to the LSTM Autoencoder in Fig 2.3. The input data has 3 timesteps and 2 features. Layer 1, LSTM (128), reads the input data and outputs 128 features with 3 timesteps for each because return_sequences=True. Layer 2, LSTM (64), takes the 3x128 input from Layer 1 and reduces the feature size to 64 the LSTM-autoencoder to enhance the performance of the LSTM-autoencoder model. The lower dimension of the input data (i.e. extracted from the LSTM-autoencoder model) are trained with the OC-SVM algorithm to achieve better classification results, whilst significantly reducing the training time. (c) We used the recently generated dataset InSDN [9] to ensure an accurate evaluation of the proposed. To generate text, you can use the decoder to reconstruct text from arbitrary input. This example trains an autoencoder to generate text. The encoder uses a word embedding and an LSTM operation to map the input text into latent vectors.
