  2. Entity–control–boundary - Wikipedia

    The classes are then refined and re-structured or reorganized as needed for the design, for example: Factoring out common behaviors in different use-case controls; Identifying a central boundary class for each kind of human actor and for each external system that would provide a consistent interface to the outside world.

    The left bottom corner shows the numbers of the class-outliers, prototypes and absorbed points for all three classes. The number of prototypes varies from 15% to 20% for different classes in this example. Fig. 5 shows that the 1NN classification map with the prototypes is very similar to that with the initial data set.

  4. Decision boundary - Wikipedia

    en.wikipedia.org/wiki/Decision_boundary

    Decision boundaries are not always clear cut. That is, the transition from one class in the feature space to another is not discontinuous, but gradual. This effect is common in fuzzy logic based classification algorithms, where membership in one class or another is ambiguous. Decision boundaries can be approximations of optimal stopping boundaries.

  5. Class (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Class_(computer_programming)

    A related concept is inner types, also known as inner data type or nested type, which is a generalization of the concept of inner classes. C++ is an example of a language that supports both inner classes and inner types (via typedef declarations). [30] [31] A local class is a class defined within a procedure or function. Such structure limits ...

  6. American middle class - Wikipedia

    en.wikipedia.org/wiki/American_middle_class

    As social classes lack clear boundaries and overlap there are no definite income thresholds as for what is considered middle class. In 2004, sociologist Leonard Beeghley identifies a male making $57,000 and a female making $40,000 with a combined households income of $97,000 as a typical American middle-class family. [ 26 ]

  7. Class diagram - Wikipedia

    en.wikipedia.org/wiki/Class_diagram

    In software engineering, a class diagram [1] in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modeling.

  8. Social class - Wikipedia

    en.wikipedia.org/wiki/Social_class

    A social class or social stratum is a grouping of people into a set of hierarchical social categories, [1] the most common being the working class, middle class, and upper class. Membership of a social class can for example be dependent on education, wealth, occupation, income, and belonging to a particular subculture or social network. [2]

  9. Linear discriminant analysis - Wikipedia

    en.wikipedia.org/wiki/Linear_discriminant_analysis

    For instance, the classes may be partitioned, and a standard Fisher discriminant or LDA used to classify each partition. A common example of this is "one against the rest" where the points from one class are put in one group, and everything else in the other, and then LDA applied. This will result in C classifiers, whose results are combined.
