How can we see the z value , which is the reconstruction of x (dataset )

Please see the link : http://deeplearning.net/tutorial/dA.html

Answer 1

The function "get_reconstructed_input" will return a Theano variable that represent z from the hidden representation. Check the function "get_cost_updates" It use it to train the model.

   tilde_x = self.get_corrupted_input(self.x, corruption_level)
   y = self.get_hidden_values( tilde_x)
   z = self.get_reconstructed_input(y)

If you don't want to train the model, you can do this:

   y = self.get_hidden_values(self.x)
   z = self.get_reconstructed_input(y)

To make an executable function that compute this:

f = theano.function([x], z)
