Implementation of PCA, PCA whitening and ZCA whitening in 2D
Implementation of PCA and ZCA whitening, and applying them to image patches taken from natural images.
An unsupervised learning algorithm that applies back propagation, setting the target values to be equal to the inputs. Also, we impose a sparsity constraint on the hidden units, then the autoencoder will still discover interesting structure in the data, even if the number of hidden units is large.
