The essence of exploration is acting to try to decrease uncertainty. We propose a new methodology for representing uncertainty in continuous-state control problems. Our approach, multi-resolution exploration (MRE), uses a hierarchical mapping to identify regions of the state space that would benefit from additional samples. We demonstrate MRE’s broad utility by using it to speed up learning in ...

Super-resolution reconstruction algorithms perform a fusion of several low quality images of the same scene into a single improved quality image. As opposed to this STATIC recovery problem, in this paper we deene a DYNAMIC super-resolution task: the restoration of a blurred, decimated, and noisy image sequence. We rst model this problem through state-space equations, showing that this problem c...

Seafloor topography and grain size distribution are pivotal features in marine coastal environments, able to influence benthic community structure ecological processes at many spatial scales. Accordingly, there is a strong interest multiple research disciplines obtain seafloor geological and/or habitat maps. The aim of this study was provide novel, automatic simple model high-resolution maps, u...
