The neural refiner corrects calibrated eye-trackers’ screen coordinates using known targets, combining ranked candidate corrections in a neural network trained with perturbed predictions. On disjoint test locations, mean angular error fell from 1.53° raw to 0.96°, versus 1.03° for the strongest classical method. Lower residual error was associated with higher game scores; evaluation used one device and an in-population neural split.
