arXiv:2602.04139v2 Announce Type: replace Abstract: Neural operators provide a powerful framework for learning discretization invariant mappings between function spaces, but standard deterministic models do not capture predictive uncertainty. We introduce diffusion last layer (DLL), a modular probabilistic output head for neural operator backbones. DLL represents target fields through an input dependent low rank expansion inspired by the Karhunen-Lo\'eve expansion and learns a conditional diffusion model over the corresponding coefficient space. This design enables efficient distributional mod
The accelerating pace of AI development necessitates increasingly sophisticated models that can handle uncertainty, especially in complex scientific and engineering domains.
This breakthrough advances the reliability and applicability of AI in critical fields by enabling models to quantify and communicate their uncertainty, moving beyond deterministic predictions.
AI models will be able to provide not just a prediction but also a robust estimate of its accuracy, making them more trustworthy for decision-making in sensitive applications.
