  2. Foil (narrative) - Wikipedia

    en.wikipedia.org/wiki/Foil_(narrative)

    Don Quixote and his sidekick Sancho Panza, as illustrated by Gustave Doré: the characters' contrasting qualities [1] are reflected here even in their physical appearances. In any narrative, a foil is a character who contrasts with another character, typically, a character who contrasts with the protagonist, in order to better highlight or differentiate certain qualities of the protagonist.

  3. FOIL method - Wikipedia

    en.wikipedia.org/wiki/FOIL_method

    In elementary algebra, FOIL is a mnemonic for the standard method of multiplying two binomials [1] —hence the method may be referred to as the FOIL method. The word FOIL is an acronym for the four terms of the product: The general form is. Note that a is both a "first" term and an "outer" term; b is both a "last" and "inner" term, and so forth.

  4. First-order inductive learner - Wikipedia

    en.wikipedia.org/wiki/First-order_inductive_learner

    Developed in 1990 by Ross Quinlan, [1] FOIL learns function-free Horn clauses, a subset of first-order predicate calculus. Given positive and negative examples of some concept and a set of background-knowledge predicates, FOIL inductively generates a logical concept definition or rule for the concept. The induced rule must not involve any ...

  5. Characterization - Wikipedia

    en.wikipedia.org/wiki/Characterization

    Characterization or characterisation is the representation of characters (persons, creatures, or other beings) in narrative and dramatic works. The term character development is sometimes used as a synonym. This representation may include direct methods like the attribution of qualities in description or commentary, and indirect (or "dramatic ...

  6. Algorithm characterizations - Wikipedia

    en.wikipedia.org/wiki/Algorithm_characterizations

    Algorithm characterizations. Algorithm characterizations are attempts to formalize the word algorithm. Algorithm does not have a generally accepted formal definition. Researchers [ 1] are actively working on this problem. This article will present some of the "characterizations" of the notion of "algorithm" in more detail.

  7. Characterization (materials science) - Wikipedia

    en.wikipedia.org/wiki/Characterization...

    Characterization, when used in materials science, refers to the broad and general process by which a material's structure and properties are probed and measured. It is a fundamental process in the field of materials science, without which no scientific understanding of engineering materials could be ascertained. [1][2] The scope of the term ...

  8. AdS/CFT correspondence - Wikipedia

    en.wikipedia.org/wiki/AdS/CFT_correspondence

    t. e. In theoretical physics, the anti-de Sitter/conformal field theory correspondence (frequently abbreviated as AdS/CFT) is a conjectured relationship between two kinds of physical theories. On one side are anti-de Sitter spaces (AdS) that are used in theories of quantum gravity, formulated in terms of string theory or M-theory.

  9. Cryptographic hash function - Wikipedia

    en.wikipedia.org/wiki/Cryptographic_hash_function

    A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of bits) that has special properties desirable for a cryptographic application: [1] finding an input string that matches a given hash value (a pre-image) is infeasible, assuming all input strings are equally likely.
