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. WebTraining DNNs are normally memory and computationally expensive. Therefore, we explore greedy layer-wise pretraining.

WebA greedy layer-wise training algorithm was proposed to train a DBN [1]. The proposed algorithm conducts unsupervised training on each layer of the network using the output on the G𝑡ℎ layer as the inputs to the G+1𝑡ℎ layer. Fine-tuning of the parameters is applied at the last with the respect to a supervised training criterion.
