M$^3$: Reframing Training Measures for Discretized Physical Simulations

Researchers introduce M³ (Multi-scale Morton Measure), a framework that improves neural surrogate models for physical simulations by addressing training bias from discretized data sampling. The method achieves up to 4.7× error reduction in volumetric cases and maintains superior performance even with 90% data reduction, demonstrating that data distribution strategy significantly impacts operator learning efficiency.
