In this paper we consider the recovery of missing regions in images and we compare the performance of two recent prediction algorithms that utilize sparse recovery. The first algorithm is based on recent work that tries to find sparse atomic decompositions (AD) using l1-norm regularization, 3, 16 while the second algorithm employs iterated denoising (ID). 8 Experimental results indicate that ID...

The paper focuses on practical aspects of decomposing OWL ontologies into logically coherent fragments, called atoms, and maintaining large ontologies in the decomposed form. While the recently proposed atomic decomposition exhibits some very attractive formal properties and promises important applications, e.g., module extraction, its practical applicability has been far from clear. Two partic...

Abstract We consider the problem of recovering three-dimensional atomic structure a flexible macromolecule from heterogeneous cryogenic electron microscopy (cryo-EM) dataset. The dataset contains noisy tomographic projections electrostatic potential macromolecule, taken different viewing directions, and in case, each cryo-EM image corresponds to conformation macromolecule. Under assumption that...

It has been observed that design of complex objects such as software requires both decomposition by form (atomic objects) and decomposition by function (nesting) in order to reduce the design to a set of manageable components. However, the object-oriented design paradigm mostly supports decomposition by form. This paper uses a simple example to motivate the need for nesting (decomposition by fu...
