Learned imaging with constraints and uncertainty quantification

Ali Siahkoohi
Advisor: Prof. Felix Herrmann

ABSTRACT

We outline new approaches to incorporate ideas from convolutional networks into wave-based least-squares imaging. The aim is to combine hand-crafted constraints with deep convolutional networks allowing us to directly train a network capable of generating samples from the posterior. The main contributions include combination of weak deep priors with hard handcrafted constraints and a possible new way to sample the posterior.
