Abstract: We study the #InverseProblem of locating gas leaks from line-of-sight concentration measurements using a convection–diffusion model with the source term a Radon measure. By imposing sparsity-promoting regularisation on this measure, we recover point sources—identifying both their locations and intensities—rather than diffuse approximations. We jointly estimate the underlying physical convection (wind) and diffusion parameters.

New publication https://doi.org/10.1103/PhysRevB.111.205143
New algorithm for the #inverseproblem of Kohn-Sham #densityfunctionaltheory (#dft), i.e. to find the #potential from the #density.
Outcome of a fun collaboration of @herbst with the group of Andre Laestadius at #oslomet to derive first mathematical error bounds for this problem

First day of “Deep learning, image analysis, inverse problems, and optimization (DIPOpt)” was very fruitful. Three talks by Martin Storath, Odyssée Merveille, and Xiaohao Cai. In addition, I had the chance to present a poster on Electron Ptychography.
