string reduction
A reduction system where an expression is represented as a
string of function names, constants and parentheses. It is
reduced by replacing parts of the string representing subterms
by their value.
It is harder to represent sharing of subexpressions in string
reduction than in graph reduction.

Dimensionality reduction
Dimensionality reduction, or dimension reduction, is the transformation of data from a high-dimensional space into a low-dimensional space so that the low-dimensional representation retains some meaningful properties of the original data, ideally close to its intrinsic dimension. Working in high-dimensional spaces can be undesirable for many reasons; raw data are often sparse as a consequence of the curse of dimensionality, and analyzing the data is usually computationally intractable (hard to control or deal with).
String (computer science)
DATA TYPE REPRESENTING A FINITE SEQUENCE OF ENCODED CHARACTERS

In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. The latter may allow its elements to be mutated and the length changed, or it may be fixed (after creation).
Great Reduction
LAND REFORMS IN SECOND MILLENNIUM SWEDEN; A TAKING-BACK OF POSSESSIONS FROM THE NOBILITY BY THE CROWN
Great Reduction (Sweden); Reduction (Sweden)
In the Great Reduction of 1680, by which the ancient landed nobility lost its power base, the Swedish Crown recaptured lands earlier granted to the nobility. Reductions () in Sweden and its dominions were the return to the Crown of fiefs that had been granted to the Swedish nobility.
Selective reduction
ABORTION OF ONE OR MORE (BUT NOT ALL) FETUSES IN A MULTIPLE PREGNANCY
Fetal reduction; Pregnancy reduction, multifetal; Selective fetal reduction; Selective termination
Selective reduction is the practice of reducing the number of fetuses in a multiple pregnancy, such as quadruplets, to a twin or singleton pregnancy. The procedure is also called multifetal pregnancy reduction.

Eight-string; 8 string guitar; 8-String Guitar; 8-string guitar; Eight string guitar; Eight-string guitars; Eight string guitars
An eight-string guitar is a guitar with eight strings, or one more than the Russian guitar's seven. Eight-string guitars are less common than six- and seven-string guitars, but they are used by a few classical, jazz, and metal guitarists.
Reduction of capital

Capital reduction; Reduction of the capital; Reduction of capital stock
Reduction of capital or capital reduction is to decrease stock of a company. During reduction of capital, sometimes the company returns a portion of the stock of a company to shareholder.
C++ string handling
CLASS IN THE C++ STANDARD LIBRARY THAT REPRESENTS A STRING OF CHARACTERS
Std::string; C++ string; C str (C++); C str(); Str (C++); String (C++); Std::wstring; Std::u16string; Std::u32string; Std::basic string; Std::u8string
The C++ programming language has support for string handling, mostly implemented in its standard library. The language standard specifies several string types, some inherited from C, some designed to make use of the language's features, such as classes and RAII.

A twelve-string guitar (or 12-string guitar) is a steel-string guitar with 12 strings in six courses, which produces a thicker, more ringing tone than a standard six-string guitar. Typically, the strings of the lower four courses are tuned in octaves, with those of the upper two courses tuned in unison.

Dimensionality reduction
Dimensionality reduction, or dimension reduction, is the transformation of data from a high-dimensional space into a low-dimensional space so that the low-dimensional representation retains some meaningful properties of the original data, ideally close to its intrinsic dimension. Working in high-dimensional spaces can be undesirable for many reasons; raw data are often sparse as a consequence of the curse of dimensionality, and analyzing the data is usually computationally intractable (hard to control or deal with). Dimensionality reduction is common in fields that deal with large numbers of observations and/or large numbers of variables, such as signal processing, speech recognition, neuroinformatics, and bioinformatics.
Methods are commonly divided into linear and nonlinear approaches. Approaches can also be divided into feature selection and feature extraction. Dimensionality reduction can be used for noise reduction, data visualization, cluster analysis, or as an intermediate step to facilitate other analyses.
