Solving Inverse Problems with Model Mismatch using Untrained Neural Networks within Model-based Architectures

no code implementations7 Mar 2024 Peimeng Guan, Naveed Iqbal, Mark A. Davenport, Mudassir Masood

Model-based deep learning methods such as \emph{loop unrolling} (LU) and \emph{deep equilibrium model} (DEQ) extensions offer outstanding performance in solving inverse problems (IP).

Learned Proximal Operator for Solving Seismic Deconvolution Problem

no code implementations19 Jul 2023 Peimeng Guan, Naveed Iqbal, Mark A. Davenport, Mudassir Masood

Due to the sparse nature of the reflectivity sequence, spike-promoting regularizers such as the $\ell_1$-norm are frequently used.

Loop Unrolled Shallow Equilibrium Regularizer (LUSER) -- A Memory-Efficient Inverse Problem Solver

no code implementations10 Oct 2022 Peimeng Guan, Jihui Jin, Justin Romberg, Mark A. Davenport

In inverse problems we aim to reconstruct some underlying signal of interest from potentially corrupted and often ill-posed measurements.
