Bayesian imaging inverse problem with scattering transform
Astronomy & AstrophysicsBayesian imaging inverse problems in astrophysics and cosmology remain challenging, particularly in low-data regimes, due to complex forward operators and the frequent lack of well-motivated priors for non-Gaussian signals.
