Here’s the underlying problem with their error estimate. As the number of observations goes up, the error bar decreases by one divided by the square root of the number of observations. And that means if we want to get one more decimal in our error, we have to have a hundred times the...
To provide a meta analysis over all PAH studies, the analytical data of all single studies were combined and descriptive statistics were calculated. No weighting between studies was conducted. The values of non-detectable results were set at the limit of detection to obtain the final distribu- ...
The most common gene selection approach is so-called gene ranking. It is a univariate approach in the sense that each gene is evaluated individually with respect to a certain criterion that represents class discrimination ability. The criteria often used are e.g., t-statistics, the signal-to-...
To get a better understanding of ArcFace's superiority, we give the detailed angle statistics on training data (CA- SIA) and test data (LFW) under different losses in Table 3. We find that (1) Wj is nearly synchronised with em- bedding feature centre for Arc...
Genome statistics and analysis Phylogenetic 16S rRNA gene sequence analysis grouped Dsc1, 2 and 3 within the previously termed 'subphylum II' clade of the Chloroflexi (Inagaki et al., 2006). All nine known Dehalococcoidetes species (Dehalococcoides mccartyi strain BAV1, CBDB1, VS, GT, DCMB5...
The two most straightforward statistics for characteriz- ing the margin distribution are the first- and second-order statistics, that is, the mean and the variance of the mar- gin. Formally, denote X as the matrix whose i-th column is ϕ(xi), i.e., X = [ϕ(x1) . . . ϕ...
