In the case of multi-parameter full-waveform inversion, the computation of the additional Hessian terms that contain derivatives with respect to more than one type of parameter is necessary. If a simple gradient-based minimization is used, different choices of parameterization can be interpreted as different preconditioners that change the condition number of the Hessian. If the non-linear inverse problem is well-posed, then the inversion should converge to a band-limited version of the true…
