Efficient stochastic Hessian estimation for full waveform inversion

Efficient stochastic Hessian estimation for full waveform inversion

In this abstract we present a method that allows arbitrary elements of the approximate Hessian to be estimated simultaneously. Preliminary theoretical and numerical investigations suggest that the number of forward models required for this procedure does not increase with the number of shots. As the...
