Greedy layerwise pre-training

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. WebIn the case of random initialization, to obtain good results, many training data and a long training time are generally used; while in the case of greedy layerwise pre-training, as the whole training data set needs to be used, the pre-training process is very time-consuming and difficult to find a stable solution.

Webtraining process, which led researchers to exploit a pre-training phase that allowed them to initialize network weights in a region near a good local optimum [4, 5]. In these studies, greedy layerwise pre-training was per-formed by applying unsupervised autoencoder models layer by layer, thus training each layer to provide a Webof greedy layer-wise pre-training to initialize the weights of an entire network in an unsupervised manner, followed by a supervised back-propagation step. The inclusion of the unsupervised pre-training step appeared to be the missing ingredient which then lead to significant improvements over the conventional training schemes.

WebPreviously, greedy layerwise training were com- monly used for unsupervised pre-training of deep neu- ral networks[1] with a target of overcoming the initializa- tion problem in training a deep neural network. It has been proved that greedy layerwise unsupervised training can serve as a good weight initialization for optimization. WebGreedy layer-wise unsupervsied pretraining name explanation: Gready: Optimize each piece of the solution independently, on piece at a time. Layer-Wise: The independent pieces are the layer of the network. …

WebApr 7, 2024 · Then, in 2006, Ref. verified that the principle of the layer-wise greedy unsupervised pre-training can be applied when an AE is used as the layer building block instead of the RBM. In 2008, Ref.
