Mission

Characterise the conditions under which learned surrogates for physical simulation depart from the simulation they approximate.

ScopeExisting simulation archives and published surrogate evaluations.

Findings

Learned surrogates fail undetectably in the tails

For the surrogates examined, error against the simulation grows superlinearly with distance from the training distribution, and nothing in the surrogate output signals it. Using one without an independent check is therefore unsafe precisely where the answer matters most.
