A low-rank approximation for large-scale 3D controlled-source electromagnetic Gauss-Newton inversion
Publikováno v:
GEOPHYSICS. 81:E211-E225
We have developed an approximation to the Hessian for inversion of 3D controlled source electromagnetic data. Our approach can considerably reduce the numerical complexity in terms of the number of forward solutions as well as the size and complexity

Use of controlled-source electromagnetics for increasingly challenging exploration applications has led to the requirement for more powerful 3D inversion approaches. For 3D cases, application of Gauss-Newton algorithms is limited by the computational

Decomposing the Hartree-Fock one-electron density matrix and a virtual pseudodensity matrix, we obtain an orthogonal set of normalized molecular orbitals with local character to be used in post-Hartree-Fock calculations. The applicability of the proc

We introduce a response function formalism that enables smaller number of parameters than that defined in standard coupled cluster response theory. This is essential in the development of reduced scaling methods. The formalism is general and it appli
