Hello!

I’m relatively new to Julia. This year I saw the JuliaCon and I’m trying to use it for my Master Thesis. I need to fit data from a simulation to a Foster series but I can’t really choose the best tool available in Julia to do so.

In the one hand, I have thought of training a *neural network* with ‘artificial data’ (generated by me) so that when I fed it with the data from the simulation it could extract the coefficients and constants of the series that fit the curve.

On the other hand, maybe traditional approaches like non-linear least squares could do the trick. However, the curve is rather sensitive because of the poles.

Another issue is that I don’t exactly know the number of terms used in the series. Maybe poles at zero or infinity are not present, and it is just LC resonators, or maybe just one LC resonator can fit it nicely.

Which would be the best way to start with?

Thanks!
