A Learned Born Series for Highly-Scattering Media
This addresses wave propagation problems in fields like acoustics or imaging, but it is incremental as it builds on existing Born series methods.
The paper tackles solving the wave equation in highly-scattering media by introducing the learned Born series (LBS), which trains components from a convergent Born series to achieve significantly higher accuracy with comparable computational cost, as errors decrease with more learned iterations.
A new method for solving the wave equation is presented, called the learned Born series (LBS), which is derived from a convergent Born Series but its components are found through training. The LBS is shown to be significantly more accurate than the convergent Born series for the same number of iterations, in the presence of high contrast scatterers, while maintaining a comparable computational complexity. The LBS is able to generate a reasonable prediction of the global pressure field with a small number of iterations, and the errors decrease with the number of learned iterations.
