I am using the Mathematica neural network package to analyse data. I want to build a neural network with 3 hidden layers. I want the neurons in the input layer, 2nd hidden layer and the output layer to be linear. The neurons in the first and third hidden layer should have a sigmoidal activation function. I haven't found a way to change the activation function in certain layers only. It is possible to change the activation from linear to sigmoidal in the output layer, and it is also possible to change to activation function to any function for ALL layers. Can somebody help me on this problem. Thanks, Peter
