PE-CSNet: An equivariant network architecture with learnable patch-based sparse representation
Kai Li, Haitao Long, Bo Zhang +2
Compressive sensing (CS) enables accurate signal reconstruction from sparse measurements and is widely applied in medical imaging, remote sensing, and image compression. However, d…

Convergent and efficient iteratively regularized contrast source inversion-type methods for inverse medium scattering problems
Qiao Hu, Bo Zhang, Haiwen Zhang
The contrast source inversion (CSI) method and the subspace-based optimization method (SOM) are first proposed in 1997 and 2009, respectively, and subsequently modified. The two me…

A deep learning approach to inverse medium scattering: Learning regularizers from a direct imaging method
Kai Li, Bo Zhang, Haiwen Zhang
This paper aims to solve numerically the two-dimensional inverse medium scattering problem with far-field data. This is a challenging task due to the severe ill-posedness and stron…
