Derivative of radial basis transfer function
Syntax
dA_dN = dradbas(N,A)
Description
dradbas is the derivative function for radbas.
dradbas(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 radbas neurons.
N = [0.1; 0.8; -0.7];
We calculate the layer's output A with radbas and then the derivative of A with respect to N.
A = radbas(N)
Algorithm
The derivative of radbas is calculated as follows:
d = -2*n*a
