Hi, everyone! I encountered some problem when using GRNN in neural network tool box. Spread is the only variable need to be determined in GRNN. I have tried different values for spread, the curve fitting capability for training data is good, but the interpolation for regions where training data is unavailiable is very poor. How can I improve the interpolation capability by using GRNN? Thanks!

Not enough information:
size(input)?
size(target)?
How are input and target scaled?
What range of spread did you use?
