Web7 mei 2024 · For that reason, models based on deep learning, such as a recurrent neural network (RNN), variational autoencoder (VAE), and long short-term memory (LSTM), have increased in the past few years. Furthermore, the number of features extracted from raw network data, which an IDS needs to examine, is usually large even for a small network. WebThe architecture incorporates an autoencoder using convolutional neural networks, and a regressor using long-short term memory networks. The operating conditions of the process are added to autoencoder’s latent space to better constraint the regression problem. The model hyper-parameters are optimized using genetic algorithms. Web20 sep. 2024 · The encoder portion of the autoencoder is typically a feedforward, densely connected network. The purpose of the encoding layers is to take the input data and compress it into a latent space representation, generating a new representation of the data that has reduced dimensionality. george catlin american indian portraits
