Solution of physics-based inverse problems using conditional generative adversarial networks with full gradient penalty

no code implementations8 Jun 2023 Deep Ray, Javier Murgoitio-Esandi, Agnimitra Dasgupta, Assad A. Oberai

The cWGAN developed in this work differs from earlier versions in that its critic is required to be 1-Lipschitz with respect to both the inferred and the measurement vectors and not just the former.

Uncertainty quantification for ptychography using normalizing flows

no code implementations1 Nov 2021 Agnimitra Dasgupta, Zichao Wendy Di

Ptychography, as an essential tool for high-resolution and nondestructive material characterization, presents a challenging large-scale nonlinear and non-convex inverse problem; however, its intrinsic photon statistics create clear opportunities for statistical-based deep learning approaches to tackle these challenges, which has been underexplored.

Simultaneous Reconstruction and Uncertainty Quantification for Tomography

no code implementations29 Mar 2021 Agnimitra Dasgupta, Carlo Graziani, Zichao Wendy Di

Tomographic reconstruction, despite its revolutionary impact on a wide range of applications, suffers from its ill-posed nature in that there is no unique solution because of limited and noisy measurements.
