It addresses a practical tuning problem for researchers using radial basis functions, but the contribution appears incremental.
The paper provides criteria for selecting the shape parameter in multiquadric radial basis functions, which is important for approximation tasks.
In this paper we present criteria for the choice of the shape parameter c contained in the famous radial function multiquadric. It may be of interest to RBF people and all people using radial basis functions to do approximation.
