Gramian inversion

WebPrinciples of joint inversion using Gramian constraints Let us consider forward geophysical problems for multiple geophysical data sets. These problems can be described by the following operator relationships: () = (), =1,2,3,⋯, ; (1) where, in a general case, () is a nonlinear operator, WebApr 6, 2024 · Joint inversion based on a correlation constraint utilizes a linear correlation function as a structural constraint. The linear correlation function contains a denominator, which may result in a singularity as the objective function is optimized, leading to an unstable inversion calculation. To improve the robustness of this calculation, this paper …
