The original work on stacked denoising autoencoders is here (PDF). If you want to use a neural network as you classifier then you could continue with more layers after that and then run backprop on that all the way to the start thus achieving better results.

You theoretical could also do some sort of fine tuning on the network as you could also form a 64 -> 32 -> 16 -> 32 -> 64 network and fine tune the parameters, but that probably isn't necessary.Īfter those steps, you then take you input data in 64 dimensional space and push it through 64 -> 32 -> 16 -> your classifier.

32 -> 16 -> 32) and go forwards from there. 64 -> 32 -> 64) with backprogogation and your noise-free input as the output as you would a typical neural network then push your data through the first layer into 32 dimensional space and run the same process (i.e. My interpretation of the stacked denoising autoencoder is you train the first autoencoder (i.e. Sorry if this sounds like a trivial question. Run final DAE layer through a supervised layer such as an SVM.layer 2->3) to train the next layer? Or would I have to run another sample through the network and then use that to train the next layer?If we use the weights from layer 2->3 wouldn't we only have one sample set to train the next autoencoder? If this is the case then would the weights just be the randomly generated initial values of the Weighting matrix? Train a neural net with Input:, Output: & then BACKPROPįor the next DAE do I use the weights from the last layer (i.e.Corrupt each training sample with gaussian noise.

So I am training a Stacked Denoising AutoEncoder with 3 layers per AutoEncoder.
