Approximate inversion of the wave-equation Hessian via randomized matrix probing
Letourneau, Pierre-David; Demanet, Laurent; Calandra, Henri (Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)We present a method for approximately inverting the Hessian of full waveform inversion as a dip-dependent and scale-dependent amplitude correction. The terms in the expansion of this correction are determined by least-squares ...
