WebWe hypothesize that three aspects of this strategy are particularly important: first, pre-training one layer at a time in a greedy way; second, using unsupervised learning at each layer in order to preserve information from the input; and finally, fine-tuning the whole network with respect to the ultimate criterion of interest. We first extend ... WebTo understand the greedy layer-wise pre-training, we will be making a classification model. The dataset includes two input features and one output. The output will be classified into …

"WebMay 6, 2014 · Traditionally, when generative models of data are developed via deep architectures, greedy layer-wise pre-training is employed. In a well-trained model, the lower layer of the architecture models the data distribution conditional upon the hidden variables, while the higher layers model the hidden distribution prior.
