Operator-Informed Gaussian Processes for Complex Helmholtz Wavefields: From Synthetic Benchmarks to In Vivo Brain Elastography
A real-imaginary 'real2' construction lets operator-informed Gaussian processes solve complex Helmholtz problems, reaching 0.77 correlation with measured brain curl wavefields but with uncalibrated posterior uncertainty.
