Supervised and unsupervised training of deep autoencoder
Deep learning has proven to be a very useful approach to learn complex data. Recent research in the fields of speech recognition, visual object recognition, natural language processing shows that deep generative models, which contain many layers of latent features, can learn complex data very efficiently. An autoencoder neural network with multiple layers can be used as a deep network to learn complex patterns in data. As training a multiple layer neural network is time consuming, a pre-training step has been employed to initialize the weights of a deep network to speed up the training process. ...
