Oct 26, 2019 · An autoencoder is a special type of neural network that copies the input values to the output values as shown in Figure (B). It does not require the target variable like the conventional Y, thus is categorized as unsupervised learning. You may ask why we train the model if the output values are set to equal to the input values. May 08, 2018 · Autoencoders are a type of generative model used for unsupervised learning. Autoencoders learn some latent representation of the image and use that to reconstruct the image. On a first glance, an autoencoder might look like any other neural network but unlike others, it has a bottleneck at the centre. Download Conjugate Gradient code minimize.m ; Download Autoencoder_Code.tar which contains 13 files OR download each of the following 13 files separately for training an autoencoder and a classification model: mnistdeepauto.m Main file for training deep autoencoder The code that builds the autoencoder is listed below. The tensor named ae_input represents the input layer that accepts a vector of length 784. This tensor is fed to the encoder model as an input.

The information bottleneck is the key to helping us to minimize this reconstruction loss; if there was no bottleneck, information could flow too quickly from the input to the output, and the network would likely overfit from learning generic representations. The ideal autoencoder is both of the following:
An autoencoder is a neural network which is trained to replicate its input at its output. Autoencoders can be used as tools to learn deep neural networks. Training an autoencoder is unsupervised in the sense that no labeled data is needed. The training process is still based on the optimization of a cost function.
