Although sparse representation and sparse recovery algorithms for colocated multiple-input multiple-output (MIMO) radar have received much attention, incoherence of the sensing matrix received few discussions.
Although sparse feature learning effectively learns the feature from the data, appropriate preprocessing is a prerequisite to obtaining a good feature.
Although sparse representation can be used for solving a system of linear equations that are overdetermined as seen in [4], it has also shown promise for underdetermined systems as demonstrated in robust face recognition studies such as [39].
Although sparse compared with studies of European glaciers, studies of the Illecillewaet are detailed by North American standards.
Although SPARSE improved prediction quality and speed over LocARNA, these results suggest even more general conclusions.
Although sparse Nhlh2 expression was transiently observed in E17.5 embryos (Fig. 5E,F), expression of this gene was absent in adult mutants (Fig. 5G,H).
Although sparse, there is some evidence that migration of adult children for economic reasons can negatively affect both mental and physical health of aging parents [ 15].
Although sparse, dynamic data and reconstructions in all three studies implied that tumour uptake of choline is rapid and that choline uptake and tumour-to-background ratios do not improve when scanning is prolonged.
Although sparse in the rodent brain, the MeApd is a primary site of aromatase expression, and sexual dimorphisms in MeA regional volume, cell number, and neural connectivity are mediated by aromatase-dependent sex-steroid signaling (see Cooke et al., 1999; McCarthy, 2008).
Dr. Mark Hurwitz of the University of California at Berkeley, the principal mission scientist, said the gas in this region, although sparse, was extremely hot, at 1.8 million degrees Fahrenheit, and radiated most of its energy in the little-studied extreme ultraviolet region of the electromagnetic spectrum.
This indicates that using nested array structure, although sparse samples are obtained, the degrees of freedom is enhanced, 2 [ ( N 1 + 1 ) N 2 − 1 ] + 1 = 2 ( N 1 + 1 ) N 2 − 1. (5).
