- kranner 7y agoCurve fitting does generalise to unseen data, and can even do it well if the training data was representative of the test data.
- enriquto 7y agoI do not understand what you mean. The whole point of curve fitting is to evaluate your curve at points that were not seen.
- 8note 7y agoas long as you're interpolating, it should do just fine. if you're extrapolating, it'll depend on whether you've assumed the right boundary conditions, but that's true for any model
- enriquto 7y agoThe difference between interpolation and extrapolation is not that relevant in dimensions higher than 1.
