If the hidden layers are larger than the input layer, an autoencoder can potentially learn the identity function and become useless. However, experimental results have shown that autoencoders might still learn useful features in these cases..Is it possible to train an autoencoder with ~ units in the input layer and , units in the hidden layer in only GPUs? Why do the number of neurons in the hidden layer of an autoencoder need to be less than the input output layer?.Now I feed it into autoencoder neural network having neurons in input layer, neurons in hidden layer and neurons in output layer. I expect to have output of output layer neuron to be same as .How do I determine the number of hidden layers and number of nodes in each hidden layer of autoencoder? What is the best way to figure out how many hidden layer neurons you need for your project? If a larger number of hidden layers in an artificial neural net allow for a greater level of abstraction from the input data, what is the sign .The autoencoder layers were combined with the ‘stack’ function, which links only the encoders. However, in my case I would like to create a hidden layer network that reproduces the input encoder decoder structure ..Params = [self.W, self.W, self.b, self.b] hidden = self.activation_function T.dot x, self.W self.b output = T.dot hidden,self.W self.b Autoencoder isn’t PCA.
