Derivative of saturating linear transfer function
Syntax
Description
dsatlin is the derivative function for satlin.
dsatlin(N,A)
takes two arguments,
N - S
x Q
net input.
A - S
x Q
output.
and returns the S
x Q
derivative dA/dN.
Examples
Here we define the net input N for a layer of 3 satlin neurons.
N = [0.1; 0.8; -0.7];
We calculate the layer's output A with satlin and then the derivative of A with respect to N.
A = satlin(N) dA_dN = dsatlin(N,A)
Algorithm
The derivative of satlin is calculated as follows:
d = 1, if 0 <= n <= 1; 0, otherwise.
