R. Kosiorek, S. Sabour, Y.W. in Reducing the Dimensionality of Data with Neural Networks Edit An Autoencoder is a bottleneck architecture that turns a high-dimensional input into a latent low-dimensional code (encoder), and then performs a reconstruction of the input with this latent code (the decoder). The autoencoder uses a neural network encoder that predicts how a set of prototypes called templates need to be transformed to reconstruct the data, and a decoder that is a function that performs this operation of transforming prototypes and reconstructing the input. 0000014336 00000 n In a simple word, the machine takes, let's say an image, and can produce a closely related picture. 2.2 The Basic Autoencoder We begin by recalling the traditional autoencoder model such as the one used in (Bengio et al., 2007) to build deep networks. 0000001668 00000 n Autoencoder is a neural network designed to learn an identity function in an unsupervised way to reconstruct the original input while compressing the data in the process so as to discover a more efficient and compressed representation. 0000041188 00000 n This viewpoint is motivated in part by knowledge c 2010 Pascal Vincent, Hugo Larochelle, Isabelle Lajoie, Yoshua Bengio and Pierre-Antoine Manzagol. If the data lie on a nonlinear surface, it makes more sense to use a nonlinear autoencoder, e.g., one that looks like following: If the data is highly nonlinear, one could add more hidden layers to the network to have a deep autoencoder. All of these produce a non-linear representation which, un-like that of PCA or ICA, can be stacked (composed) to yield deeper levels of representation.
