This is implemented in layers: sknn.ae.Layer: Used to specify an upward and downward layer with non-linear activations. As with any neural network there is a lot of flexibility in how autoencoders can be constructed such as the number of hidden layers and the number of nodes in each. Train an autoencoder with a hidden size of 50 using the training data. After training the first autoencoder, you train the second autoencoder in a similar way. An autoencoder generally consists of two parts an encoder which transforms the input to a hidden code and a decoder which reconstructs the input from hidden code. The customer could then edit this function so that it outputs the output of layer 1 (a1) (I have attached an example of how the function will look like after the changes).
