Models, fits, and wild guesses

“The goal of this work is to fill this gap in measurement capabilities with a virtual replacement for MEGS-A,” a group of researchers said in a paper ...

From where I am sitting, and without reading the article, this looks dangerously close to faking the data. It is absolutely fine to use physical models constrained by the observed parameters to infer the parameters we can't measure. Using an intrinsically inscrutable, million-parameters fit - a.k.a. the neural net - for the same purpose is a lot more problematic, but may be acceptable under certain limited circumstances and with a lot of caveats. Pretending that this is somehow a replacement for the actual measurement is not.
