In line-based tools, it matches the ending position of any line. ( ) Defines a marked subexpression, also called a capturing group, which is essential for extracting the desired part of the text (See also the next entry, \n). BRE mode requires \( \). \n: Matches what the nth marked subexpression matched, where n is a digit from 1 to 9
An n-bit LUT can encode any n-input Boolean function by storing the truth table of the function in the LUT. This is an efficient way of encoding Boolean logic functions, and LUTs with 4-6 bits of input are in fact the key component of modern field-programmable gate arrays (FPGAs) which provide reconfigurable hardware logic capabilities.
Quicksort applied to a list of n elements, again assumed to be all different and initially in random order. This popular sorting algorithm has an average-case performance of O(n log(n)), which contributes to making it a very fast algorithm in practice. But given a worst-case input, its performance degrades to O(n 2).
In the formula, A is the supplied m by n weighted matrix of term frequencies in a collection of text where m is the number of unique terms, and n is the number of documents. T is a computed m by r matrix of term vectors where r is the rank of A—a measure of its unique dimensions ≤ min(m,n).
The text in the cell is taken from the first parameter; {{yes | Sure}} would output "Sure" otherwise it defaults to "Yes". Most templates allow authors to override the default text in this way, some require text put after the template call and some also need a vertical bar in between: {{table cell template}} text or {{table cell template ...
In the case of document retrieval, queries can be based on full-text or other content-based indexing. Information retrieval is the science [ 1 ] of searching for information in a document, searching for documents themselves, and also searching for the metadata that describes data, and for databases of texts, images or sounds.
while the former is a disjunction of n conjunctions of 2 variables, the latter consists of 2 n clauses of n variables. However, with use of the Tseytin transformation , we may find an equisatisfiable conjunctive normal form formula with length linear in the size of the original propositional logic formula.
These vectors capture information about the meaning of the word based on the surrounding words. The word2vec algorithm estimates these representations by modeling text in a large corpus. Once trained, such a model can detect synonymous words or suggest additional words for a partial sentence.
