"Numerical Solution of the Inverse Scattering Problem using High-Level Representations"

Ponente: Maria Luisa Daza Torres
Lugar: Salón K201
Hora: 4:00 pm
Resumen: We use a point cloud to represent the support of a scattering obstacle; adding a shape parameter (alpha-shape) allows us to represent an arbitrary obstacle. This representation allows us to treat the inverse scattering problem in a low dimensional parameter space. We formulate the inverse scattering problem in the Bayesian frame and approach the posterior distribution in a finite-dimensional space using the alpha-shape representation. We explore the posterior distribution with an affine invariant Markov Chain Monte Carlo on the point cloud and alpha-shape parameter.
