  2. Cross-correlation - Wikipedia

    en.wikipedia.org/wiki/Cross-correlation

    For jointly wide-sense stationary stochastic processes, the definition is = ⁡ = ⁡ [() (+) ¯] The normalization is important both because the interpretation of the autocorrelation as a correlation provides a scale-free measure of the strength of statistical dependence, and because the normalization has an effect on the statistical ...

  3. Convolution - Wikipedia

    en.wikipedia.org/wiki/Convolution

    Gaussian blur can be used to obtain a smooth grayscale digital image of a halftone print. Convolution and related operations are found in many applications in science, engineering and mathematics. Convolutional neural networks apply multiple cascaded convolution kernels with applications in machine vision and artificial intelligence.

  4. Correspondence analysis - Wikipedia

    en.wikipedia.org/wiki/Correspondence_analysis

    Correspondence analysis (CA) is a multivariate statistical technique proposed [1] by Herman Otto Hartley (Hirschfeld) [2] and later developed by Jean-Paul Benzécri. [3] It is conceptually similar to principal component analysis, but applies to categorical rather than continuous data.

  5. Representation (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Representation_(mathematics)

    In mathematics, a representation is a very general relationship that expresses similarities (or equivalences) between mathematical objects or structures.Roughly speaking, a collection Y of mathematical objects may be said to represent another collection X of objects, provided that the properties and relationships existing among the representing objects y i conform, in some consistent way, to ...

  6. SIMPLE algorithm - Wikipedia

    en.wikipedia.org/wiki/SIMPLE_algorithm

    In computational fluid dynamics (CFD), the SIMPLE algorithm is a widely used numerical procedure to solve the Navier–Stokes equations. SIMPLE is an acronym for Semi-Implicit Method for Pressure Linked Equations. The SIMPLE algorithm was developed by Prof. Brian Spalding and his student Suhas Patankar at Imperial College London in the early ...

  7. Simple function - Wikipedia

    en.wikipedia.org/wiki/Simple_function

    In the mathematical field of real analysis, a simple function is a real (or complex)-valued function over a subset of the real line, similar to a step function. Simple functions are sufficiently "nice" that using them makes mathematical reasoning, theory, and proof easier. For example, simple functions attain only a finite number of values.

  8. Fuzzy set operations - Wikipedia

    en.wikipedia.org/wiki/Fuzzy_set_operations

    μ A (x) is defined as the degree to which x belongs to A.Let ∁A denote a fuzzy complement of A of type c.Then μ ∁A (x) is the degree to which x belongs to ∁A, and the degree to which x does not belong to A.

  9. GRASP (object-oriented design) - Wikipedia

    en.wikipedia.org/wiki/GRASP_(object-oriented_design)

    In object-oriented design, a pattern is a named description of a problem and solution that can be applied in new contexts; ideally, a pattern advises us on how to apply its solution in varying circumstances and considers the forces and trade-offs.
