Stochastic Multigrid Method for Blind Ptychography
Borong Zhang, Junjing Deng, Yi Jiang +1
Blind ptychography reconstructs an object and a probe from diffraction measurements collected over overlapping scan regions. We introduce a reconstruction framework with two comple…
MAGPIE: Multilevel-Adaptive-Guided Solver for Ptychographic Phase Retrieval
Borong Zhang, Qin Li, Zichao Wendy Di
We introduce MAGPIE (Multilevel-Adaptive-Guided Ptychographic Iterative Engine), a stochastic multigrid solver for the ptychographic phase-retrieval problem. The ptychographic phas…
Back-Projection Diffusion: Solving the Wideband Inverse Scattering Problem with Diffusion Models
Borong Zhang, Martín Guerra, Qin Li +1
We present Wideband Back-Projection Diffusion, an end-to-end probabilistic framework for approximating the posterior distribution induced by the inverse scattering map from wideban…
Solving the Wide-band Inverse Scattering Problem via Equivariant Neural Networks
Borong Zhang, Leonardo Zepeda-Núñez, Qin Li
This paper introduces a novel deep neural network architecture for solving the inverse scattering problem in frequency domain with wide-band data, by directly approximating the inv…
