The normalised RMS misfit is shown for 20 different inversions using unseen samples from the population L in the upper panel and population T in the lower panel. 15% white noise was added to the input seismic traces during training. The velocity models are well resolved by the FNO inversions as are the source locations. All 20 inversions are for different previously unseen models with the same statistical properties as the training velocity model sets.
