It seeks a low rank background subspace and represents the background as the linear combination of the basis spanning the subspace.
Motivated by the robust principal component analysis, infrared small target image is regarded as low-rank background matrix corrupted by sparse target and noise matrices, thus a new target-background separation model is designed, subsequently, an adaptive detection method of infrared small target is presented.
For example, when testing a set of size 14 for gene gene interactions using a low rank background kernel containing 150 SNPs, our low rank score test was ∼2000 times faster than the naïve implementation (1 s versus 32 min).
However, even when this full-rank background kernel changes in a low rank manner with every test (as it would when correcting for proximal contamination), our improvement still allows the bottleneck computation to be performed only once per dataset.
As for background, negative background performed the best in terms of the three performance indicators, positive background ranked second, and no background performed the worst.
Recently, based on a graph-based manifold ranking method, Yang et al. [39] detected saliency of the image elements by ranking the similarity to background and foreground queries.
But commonsense draws a distinction between causes and background conditions, ranking the camper's lighting of the fire among the former, and his birth and his failure to be struck down by a meteor, among the latter.
DM variants were consistently ranked higher than background variants by a large range of annotation models.
Hybridization quality was assessed by a signal score, which examined the number of untreated channel signal probes that ranked above the background (anti-genomic control) probes.
We then evaluate our proposed models by the rankings of the ground truth genes in each of the six proposed models' gene scoring vector µ and demonstrate the effects of integrating more background information in ranking.
