Operator learning zero-shot super-resolution theory explored

Researchers have theoretically investigated the phenomenon of zero-shot super-resolution in operator learning, where models trained on coarse grids can predict on finer grids without retraining. They demonstrate that this capability can be information-theoretically impossible in certain benign settings. The study identifies Hölder smoothness of output functions as a sufficient condition for zero-shot super-resolution and provides corresponding generalization bounds, with experimental validation of identified failure modes.
