New APEX Framework Enhances High-Frequency Wave Prediction with Scarce Data

Researchers have developed a new framework called APEX for predicting higher-frequency wave fields, particularly in scenarios where data for these higher frequencies is scarce. APEX leverages a lower-frequency neural operator to extract transferable amplitude information, which then guides a conditional flow-matching enhancer to reconstruct the target higher-frequency field. This approach, which separates the reuse of coarse structure from the recovery of oscillatory detail, has demonstrated superior performance over existing extrapolation and adaptation baselines on benchmarks like SimpleWave, Helmholtz, and Maxwell.
