==Answer: The outputs are the same as the inputs, i.e. y_i = x_i. The autoencoder tries to learn the identity function. Although it might seem that if the number of hidden units >= the number of input units (/output units) the resulting weights would be the trivial identity, in practice this does not turn out to be the case (probably due to the fact that the weights start so small). Sparse autoencoders, where a limited number of hidden units can be activated at once, avoid this problem even in theory.

==Where is the structure section taken from?
I was wondering if there were any book sources that could be added as reference where a similar approach in describing the autoencoder is taken. Also, what are the W and b terms? It's not very clear.
