Description
Amplitude surrogates speed up one of the most computationally expensive steps in the LHC simulation chain. We adapt the generative amplification framework to amplitude surrogates evaluated by reweighting and apply it to uncertainty-aware surrogates. We show that amplitude surrogates, like generative event generators, can exhibit generative amplification when trained on a limited set of expensive amplitude evaluations. In particular, we study gluon-associated $Z$ production and find that amplification emerges in the sparsely populated high-$p_T^Z$ tails, where it matters most.
