Greedy layer- wise training of deep networks

WebMar 4, 2024 · The structure of the deep autoencoder was originally proposed by , to reduce the dimensionality of data within a neural network. They proposed a multiple-layer encoder and decoder network structure, as shown in Figure 3, which was shown to outperform the traditional PCA and latent semantic analysis (LSA) in deriving the code layer. WebInspired by the success of greedy layer-wise training in fully connected networks and the LSTM autoencoder method for unsupervised learning, in this paper, we propose to im-prove the performance of multi-layer LSTMs by greedy layer-wise pretraining. This is one of the first attempts to use greedy layer-wise training for LSTM initialization. 3.
