A Contrast-Source Inversion Scheme Based on Stochastic Optimization and Plug-and-Play Regularization
Lingqi Gao, Hakan Bagci
An electromagnetic inversion scheme that integrates stochastic optimization (STO) and plug-and-play (PNP) regularization into contrast-source inversion (CSI), termed STO-PNP-CSI, i…

A Sparsity-Promoting Electromagnetic Inversion Method Regularized by -Norm of the Model Gradient
Lingqi Gao, Hakan Bagci
A nonlinear EM inversion method regularized by -norm of the model gradient is proposed. The -norm, defined as the ratio of -norm to $\ell_…
