Emulation, a.k.a. surrogate modelling. I n this context, it means reducing complicated physics-driven simulations to simpler/or faster ones using ML techniques. Especially popular in the ML for physics pipeline. I have mostly done this in the context of surrogate optimisation for experiments.
A recent, hyped paper that exemplifies this approach is Kasim et al. (2020), which (somewhat implicitly) uses arguments from Gaussian process regression to produce quasi-Bayesian emulations of notoriously slow simulations. I am amazed that this works.
