Small filter caches (L0 caches) can be used to obtain significantly reduced energy consumption for embedded systems, but this benefit comes at the cost of increased execution time due to frequent L0 cache misses. The Instruction Register File (IRF) is an architectural extension for providing improved access to frequently occurring instructions. An optimizing compiler can exploit an IRF by packi...

In this paper, we propose a new method for synthetic aperture radar (SAR) image despeckling via L0-minimization strategy, which aims to smooth homogeneous areas while preserve significant structures in SAR images. We argue that the gradients of the despeckled images are sparse and can be pursued by L0-norm minimization. We then formularize the despeckling of SAR images as a global L0 optimizati...

Abstract: We assume data sampled from a mixture of d-dimensional linear subspaces with spherically symmetric outliers. We study the recovery of the global l0 subspace (i.e., with largest number of points) by minimizing the lp-averaged distances of data points from d-dimensional subspaces of R , where 0 < p ∈ R. Unlike other lp minimization problems, this minimization is non-convex for all p > 0...

The two dimensional crossover from independent particle towards collective motion is studied using 2 spinless fermions interacting via a U/r Coulomb repulsion in a L× L square lattice with periodic boundary conditions and nearest neighbor hopping t. Three regimes characterize the ground state when U/t increases. Firstly, when the fluctuation ∆r of the spacing r between the two particles is larg...

in recent years, ionic liquids have been used in pharmaceutical processes. therefore, having a deep insight into the ion association behavior of ionic liquids in the presence of a drug is of particular importance. so, in this work, the molar conductivities of the ionic liquids, 1-alkyl-3-methylimidazolium bromide, [cnmim]br (n = 4, 6 and 8) in various concentrations of aspirin (asa) in acetonit...

For the study of some typical problems in finance and economics, Žitković introduced convex compactness gave many remarkable applications. Recently, motivated by random optimization variational inequalities, Guo, et al. L0-convex compactness, developed related theory normed modules further applied it to backward stochastic equations. In this paper, we extensively L0-convexly compact sets locall...

We propose a versatile framework based on random search, Sparse-RS, for score-based sparse targeted and untargeted attacks in the black-box setting. Sparse-RS does not rely substitute models achieves state-of-the-art success rate query efficiency multiple attack models: L0-bounded perturbations, adversarial patches, frames. The L0-version of outperforms all even white-box different MNIST, CIFAR...

mbedded systems are electronic systems that have permeated into many aspects of our lives. We can sense the presence of such systems in automobiles, house-hold appliances, consumer electronics and several others. In particular, demand for multimedia applications based embedded systems has been growing at an impressive rate. One of the distinguishing characteristics of such systems is that they ...
