Can we optimize heterogeneous parameters of RBF Network using Gradient Descent?

Question

There're three parameters in the Radial Basis Function Networks (RBFN).

1. Centers of RBFs
2. Width of RBFs
3. Weights of RBFs

It's a fact that Weights can be easily updated using a simple Gradient Descent. My question is: Can we optimize Centers and Widths of RBFs using Gradient Descent such that approximation will tend to be better.

Any suggestion is welcome.

Answer 1

Yes - Radial Basis Function's (RBF) centers and widths can be optimized with gradient descent.
