SPAMoE framework enhances full-waveform inversion with spectrum-aware neural operators

Researchers have developed SPAMoE, a novel framework designed to improve the efficiency and accuracy of full-waveform inversion (FWI) for subsurface velocity model reconstruction. This approach addresses the challenge of frequency entanglement in multi-scale geological features by incorporating a spectral-preserving encoder and a dynamic routing mechanism for a Mixture-of-Experts ensemble. Experiments on the OpenFWI datasets demonstrated that SPAMoE significantly reduces the mean absolute error compared to existing baselines, establishing a new architectural framework for learning-based FWI.
