Improving a surrogate model for Jet Substructure Tuning:

• Learns how the generator reacts when we change parameters, much faster than using only prof2/rivet plotting

• Builds a fast “fake MC” so we don’t rerun full simulation

• This will let us scan and minimize χ² faster

• We only run the real MC again to double-check the best fitting region

• Gitlab repo for development: https://gitlab.cern.ch/isildak/mcdnntuning/-/tree/master?ref_type=heads
