It says in the starter notebook:

“The objective for Stage 1 of this multi-stage challenge is to empirically fit a set of 1D curves without knowledge of the analytical equation…”

And the demonstration fits the X1 curve from the sample_submission table… But since we don’t have the similar curves for the Test data (we only have the starting parameters), how can we perform the curve fitting?

Sorry if I misunderstood something.Thanks!
