Domain independent post-processing with graph U-nets: Applications to Electrical Impedance Tomographic Imaging

no code implementations8 May 2023 William Herzberg, Andreas Hauptmann, Sarah J. Hamilton

We demonstrate effectiveness and flexibility of the graph U-Net for improving reconstructions from electrical impedance tomographic (EIT) measurements, a nonlinear and highly ill-posed inverse problem.

Graph Convolutional Networks for Model-Based Learning in Nonlinear Inverse Problems

1 code implementation28 Mar 2021 William Herzberg, Daniel B. Rowe, Andreas Hauptmann, Sarah J. Hamilton

This gives rise to the proposed iterative Graph Convolutional Newton-type Method (GCNM), which includes the forward model in the solution of the inverse problem, while all updates are directly computed by the network on the problem specific mesh.
