The output argument from the encoder of the second autoencoder is the input argument to the third autoencoder in the stacked network, and so on. By choosing the top principal components that explain say 80-90% of the variation, the other components can be dropped since they do not significantly bene… be a cell array of image data or an array of single image data. You feed an image with just five pixel values into the autoencoder which is compressed by the encoder into three pixel values at the bottleneck (middle layer) or latent space. I've looked at stacking Autoencoders, but it seems it only performs the encode function, not the decode. The autoencoder will be constructed using the keras package. If the autoencoder autoenc was trained Data encoded by autoenc, specified as a matrix.
