It's not related to the type of the kernel, but it is a MUST if you want to
have good results. Just scale the inputs between -1 and 1, or to the data
having zero mean and variance = 1.
Don't ask me why! It is longer than average Email letter.
Just do it, and if curious, search the papers and books for the answer.
