I currently am trying to create a three layer neural network and I want to use the back propagation.
My training data is:
Input : Output
0 | 1 : 0
1 | 1 : 2
In many articles that I've read, they use
1
f(x) = ---------
1 + e-input
to calculate the output of each neuron.
But this function can only return an output between 0.5 and 1, right? Does anyone know another function that I can use for calculating the output?
