PINNs recover conductivity features with 3-12% error using wavelets and FFE · 2 sources tracked

Researchers have developed a new framework using physics-informed neural networks (PINNs) to reconstruct conductivity features from limited boundary data in the Calderón inverse problem. The method incorporates randomized wavelet functions and Fourier-feature encoding to better represent sharp variations in conductivity. Evaluations using synthetic data show the framework can recover dominant conductivity structures with relative errors between 3% and 12%, with Fourier-feature encoding proving particularly effective for localized sharp features like inclusions and interfaces.
