For a given term t and a specific document d among a series of document D, we denote tf t, d) as term frequency which means the occurrence of term t in document d and denote idf t, D) as inverse document frequency; that is, (1) i d f (t, D ) = log | D | | { d ∈ D : t ∈ d } | + 1.
The authors point out that these terms are often used interchangeably, and that a given term may have different meanings for different organizations.
A node in the graph represents a hypothesized region of the given term, and connections are created from acoustically similar hypothesized regions.
As GO level values refer to the position of the enriched terms in the GO hierarchy tree, they can define the specificity or granularity of a given GO term and thus are a valuable parameter for terms prioritization and for inferring biological meaning from GO enrichment analysis [ 39].
These represent four possible notions of association between a given GO term and the inferred network (Yang and Leskovec, 2012).
In the case of the topology-based approach introduced by Zhang et al., f(x) is called the count of the term x, it depends only on the children of a given GO term and is numerically equal to the sum of counts of all its children.
In specific, the hypergeometric probability p that a GO term is significantly enriched in a network is calculated as: (4) where k is the number of genes in the group, G is the total number of genes, n is the number of genes in the module with a given GO term and A is the total number of genes with a given GO term.
The primary use of correlations in this article was in establishing the rank correlation between a given energy term and RMSD to the native to provide an indication of the ranking performance of the energy term on a given decoy set.
We consider the high-frequency Helmholtz equation with a given source term, and a small absorption parameter α>0.
On the question of reaching a new audience, Optimal looked at the number of people who would have been reachable by targeting a given search term, and then compared that to a brand's Facebook fans (or others who could have been targeted with existing Facebook ad units).
