Yeah, I will try to get as many as possible "extreme" cases to expand the training range. Then all testing case will be just "interpolate" , instead of "extrapolate". I heard that polynomial fit is bad for multi-input/multi-variable case. I am going to try neural networks... do you know which NN is best for such tasks? Thanks a lot, -Walala
