MLP output

Hello,

I have a quick question: In working with the mlpHiggs.C example I noticed that the NN output can be greater then 1 and less then 0. This is seen on page 83 of the manual as well.
I thought that a sigmoid function is used as an activation function and so the output should be constrained to [0,1]. What I am missing?

Thanks for your time,

Hi,
output neurons are linear, see http://root.cern.ch/root/html/TNeuron#TNeuron:description
