Structure-Driven Methodology: An Emerging Cross-Domain Paradigm
Shengchang Chen
This article proposes and articulates structure-driven methodology as an emerging cross-domain paradigm. In contrast to the objective-driven paradigm that has dominated inverse-pro…
Structure-Driven Inversion: A New Paradigm for Solving Inverse Problems
Shengchang Chen
Inverse problems are predominantly solved within the optimization-driven paradigm, which formulates the problem as objective-function minimization and approaches the solution by it…
PSDWII: Physical-Structure-Driven Waveform Inversion Imaging
Shengchang Chen
This paper proposes a Physical-Structure-Driven Waveform Inversion Imaging framework (PSDWII), grounded in the recognition that surface-recorded seismic data are directly related t…
A Spectral-Domain Pseudo-Inverse Method for True 3D Gravity Inversion
Shengchang Chen
The main difficulty in 3D gravity inversion is that surface observations lack vertical wavenumber information, making the problem underdetermined and depth resolution poor. Buildin…
A Spectral-Domain Pseudo-Inverse Construction Method for Unitary Diagonalizable Linear Inverse Problems
Shengchang Chen
Linear inverse problems are prevalent in geophysics, signal processing, image restoration, and medical imaging. Mathematically, they can be formulated as . When is ill-…
