S-cone opponency, on the other hand, is supported in the primate LGN by a much smaller group of sparse, specialized neurons (Derrington et al., 1984; Reid & Shapley, 1992), reflecting the low proportion of S-cones in the retinal cone population (∼7%; Curcio et al., 1991).
The gene regulatory network (GRN) abstraction aims at explaining the joint variability in the expression levels of a group of genes through a sparse pattern of interactions; elucidating the topology of GRNs can provide important insights in the fundamental biology of the system and suggest possible intervention points in biomedical applications.
From the emerging overview, the research objectives still appear rather sparse: a group of studies evaluated the impact of metabolic changes, due to undernourishment [ 152], low-protein [ 153], folate-deficient [ 154], zinc-deficient [ 155], obesogenic, and/or diabetogenic diets [ 149, 156– 156].
Penalized methods tend to select only one or few variables belonging to a group of correlated variables, resulting in a sparse model.
If the edge connections are sparse within a group of nodes, the corresponding traits are only weakly related and there is little propagation of fusion effect through edges in the subgroup.
Abdul travels with a group of five other male herders, sleeping under sparse thorn bushes and eating rice just once a day.
It entails the collection of (possibly sparse) data from dynamic experiments in a group of subjects and their quantitative interpretation by means of a mathematical model.
MCALESTER, Oklahoma ― Just after 11 30 a.m., two correctional workers led a group of five people past a stack of box lunches into a sparse recreation room where they would wait out the next three hours. .
The hypnotic teaser song Swords (which features on the deluxe version of AIM) is sparse and slick, fusing samples of clanging metal and arriving with a triumphant video starring a group of sword-wielding female dancers.
The common structure property of the sparse source vectors suggests the application of a group sparse reconstruction.
Thus, the underlying problem can be regarded as a group sparse reconstruction problem of locating the non-zero entries of (tilde {boldsymbol {b}}_{[l]},l=1,cdots,L).
