  2. Torus - Wikipedia

    en.wikipedia.org/wiki/Torus

    A ring torus with aspect ratio 3, the ratio between the diameters of the larger (magenta) circle and the smaller (red) circle. In geometry, a torus ( pl.: tori or toruses) is a surface of revolution generated by revolving a circle in three-dimensional space one full revolution about an axis that is coplanar with the circle.

  3. Five-qubit error correcting code - Wikipedia

    en.wikipedia.org/wiki/Five-qubit_error...

    Its logical operators are ¯ = and ¯ =. Once the logical qubit is encoded, errors on the physical qubits can be detected via stabilizer measurements. A lookup table that maps the results of the stabilizer measurements to the types and locations of the errors gives the control system of the quantum computer enough information to correct errors.

  4. Scope resolution operator - Wikipedia

    en.wikipedia.org/wiki/Scope_resolution_operator

    The scope resolution operator helps to identify and specify the context to which an identifier refers, particularly by specifying a namespace or class. The specific uses vary across different programming languages with the notions of scoping. In many languages, the scope resolution operator is written :: .

  5. Neural operators - Wikipedia

    en.wikipedia.org/wiki/Neural_operators

    Neural operators are a class of deep learning architectures designed to learn maps between infinite-dimensional function spaces. Neural operators represent an extension of traditional artificial neural networks, marking a departure from the typical focus on learning mappings between finite-dimensional Euclidean spaces or finite sets.

  7. Ellipsis (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Ellipsis_(computer...

    Incomplete code. In Perl and Raku the 3-character ellipsis is also known as the "yada yada yada" operator and, similarly to its linguistic meaning, serves as a "stand-in" for code to be inserted later. Python3 also allows the 3-character ellipsis to be used as an expressive place-holder for code to be inserted later.

  8. Prewitt operator - Wikipedia

    en.wikipedia.org/wiki/Prewitt_operator

    The Prewitt operator is used in image processing, particularly within edge detection algorithms. Technically, it is a discrete differentiation operator, computing an approximation of the gradient of the image intensity function. At each point in the image, the result of the Prewitt operator is either the corresponding gradient vector or the ...

  9. d'Alembert operator - Wikipedia

    en.wikipedia.org/wiki/D'Alembert_operator

    d'Alembert operator. In special relativity, electromagnetism and wave theory, the d'Alembert operator (denoted by a box: ), also called the d'Alembertian, wave operator, box operator or sometimes quabla operator [1] ( cf. nabla symbol) is the Laplace operator of Minkowski space. The operator is named after French mathematician and physicist ...
