ConvNetJs2 Denoising Autoencoder demo


All the other demos are examples of Supervised Learning, so in this demo I wanted to show an example of Unsupervised Learning. We are going to train an autoencoder on MNIST digits.

An autoencoder is a regression task where the network is asked to predict its input (in other words, model the identity function). Sounds simple enough, except the network has a tight bottleneck of a few neurons in the middle (in the default example only two!), forcing it to create effective representations that compress the input into a low-dimensional code that can be used by the decoder to reproduce the original input.
