the String group can be thought of as a "higher" complex spin group extension, in the sense of higher group theory since the space (,) is an example of a higher group. It can be thought of the topological realization of the groupoid B U ( 1 ) {\displaystyle \mathbf {B} U(1)} whose object is a single point and whose morphisms are the group U ( 1 ...
An aggregation is a kind of association that models a part/whole relationship between an aggregate (whole) and a group of related components (parts). A composition, also called a composite aggregation, is a kind of aggregation that models a part/whole relationship between a composite (whole) and a group of exclusively owned parts.
COBOL uses the STRING statement to concatenate string variables. MATLAB and Octave use the syntax "[x y]" to concatenate x and y. Visual Basic and Visual Basic .NET can also use the "+" sign but at the risk of ambiguity if a string representing a number and a number are together. Microsoft Excel allows both "&" and the function "=CONCATENATE(X,Y)".
Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some specific sense defined by the analyst) to each other than to those in other groups (clusters).
D provides an explicit "alias this" declaration within a type can forward into it every method and member of another contained type. [11] Dart provides mixins with default implementations that can be shared. Go type embedding avoids the need for forwarding methods. [12] Java provides default interface methods since version 8.
Bootstrap aggregating, also called bagging (from bootstrap aggregating) or bootstrapping, is a machine learning (ML) ensemble meta-algorithm designed to improve the stability and accuracy of ML classification and regression algorithms. It also reduces variance and overfitting.
The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming.The builder pattern separates the construction of a complex object from its representation.
RDFLib is a Python library for working with RDF, [2] a simple yet powerful language for representing information. This library contains parsers/serializers for almost all of the known RDF serializations, such as RDF/XML, Turtle, N-Triples, & JSON-LD, many of which are now supported in their updated form (e.g. Turtle 1.1).
