Our approach is to use cluster analysis, and specifically k-means clustering, to partition the whole test suite into two clusters, pick the cluster containing the majority of failing tests and label all passing tests within it as cct’s. We use the Euclidean metric as a distance measure and...

If, however, the current block contains pixels representing two nicely contrasted colors, the colors identified for the larger block will have a negligible impact on the resulting clusters. 2) Implementation: A fast version of this multiscale foreground-background color identification, as shown in ...

varying from 0 to 50%; iii) the number of clusters, chosen from the intervalK= [2,5]; and iv) the proportion of inliers (i.e. the percentage of samples belonging to the main cluster over all the clustered data points, disconsidering uniform noise), set withinδ= [100/K,100] percen...
To calculate trait-specificPSTvalues, we estimated the phenotypic variance between and within populations using linear hierarchical (or multilevel) models (Brommer et al.2014). Multilevel models have the advantage of fitting parameters specific to clusters of observations (Gelman and Hill2007), such...
Animals can occur singly, or in clusters (i.e., flocks, schools, herds). Grouping detections into distance categories can be especially helpful if exact distances are difficult to obtain, i.e., exact distances need only be measured to the cutpoint of each category rather than to each ...
Such modulation is periodic with the shaft rotation frequency, and can be written as [24]: N ak(t) = ∑ Akn cos(2πn frt + αk) n=1 (2) N bk(t) = ∑ Bkn sin(2πn frt + βk) n=1 (3) where Akn, Bkn are the amplitudes of the modulation function, and αk and βk...
