This paper considers the image recovery problem by taking group sparsity into account as prior knowledge. is formulated a sparse optimization over intersection of polyhedron and possibly degenerate ellipsoid. It convexly constrained with cardinality objective function. We use capped folded concave function to approximate show that solution set continuous approximation solutions are same. Moreov...

the effective factors of forward speed, cylinder rotation, and clearance between a combine’s cylinder and concave on wheat kernel breakage and seed germination were studied in karaj area using a 955 model john dear combine. this study was conducted on three levels of adjustment for each of the variables, 1.2, 1.8 and 2.5 km/hr for forward speed, 800, 900, 1000 rpm for cylinder rotation as well ...

In this paper we further develop the theory of f-divergences for log-concave functions and their related inequalities. We establish Pinsker inequalities new affine invariant entropy obtain on functional surface area lower upper bounds Kullback-Leibler divergence in terms area. The lead to L_p-affine areas convex bodies.

We consider a novel sub-class of log-location-scale models for survival and reliability data formed by restricting the density of the underlying location-scale distribution to be log-concave. These models display a number of attractive properties. We particularly explore the shapes of the hazard functions of these, LLSLC, models. A relatively elegant, if partial, theory of hazard shape arises u...
