    en.wikipedia.org/wiki/Country_code

    ISO 3166-1 alpha-2: two-letter code; ISO 3166-1 alpha-3: three-letter code; ISO 3166-1 numeric: three-digit code; The two-letter codes are used as the basis for other codes and applications, for example, for ISO 4217 currency codes; with deviations, for country code top-level domain names (ccTLDs) on the Internet: list of Internet TLDs.

  4. Word2vec - Wikipedia

    en.wikipedia.org/wiki/Word2vec

    The idea of skip-gram is that the vector of a word should be close to the vector of each of its neighbors. The idea of CBOW is that the vector-sum of a word's neighbors should be close to the vector of the word. In the original publication, "closeness" is measured by softmax, but the framework allows other ways to measure closeness.

  5. Cyclic code - Wikipedia

    en.wikipedia.org/wiki/Cyclic_code

    A negacyclic code is a constacyclic code with λ=-1. [8] A quasi-cyclic code has the property that for some s, any cyclic shift of a codeword by s places is again a codeword. [9] A double circulant code is a quasi-cyclic code of even length with s=2. [9] Quasi-twisted codes and multi-twisted codes are further generalizations of constacyclic ...

  6. Code (cryptography) - Wikipedia

    en.wikipedia.org/wiki/Code_(cryptography)

    An idiot code is a code that is created by the parties using it. This type of communication is akin to the hand signals used by armies in the field. Example: Any sentence where 'day' and 'night' are used means 'attack'. The location mentioned in the following sentence specifies the location to be attacked. Plaintext: Attack X.

  7. Word addressing - Wikipedia

    en.wikipedia.org/wiki/Word_addressing

    In order to clearly elucidate the code necessary for sub-word accesses without tying the example too closely to any particular word-addressed architecture, the following examples use MIPS assembly. In reality, MIPS is a byte-addressed architecture with direct support for loading and storing 8-bit and 16-bit values, but the example will pretend ...

  8. Linear code - Wikipedia

    en.wikipedia.org/wiki/Linear_code

    A code is defined to be equidistant if and only if there exists some constant d such that the distance between any two of the code's distinct codewords is equal to d. [4] In 1984 Arrigo Bonisoli determined the structure of linear one-weight codes over finite fields and proved that every equidistant linear code is a sequence of dual Hamming ...

  9. Reed–Muller code - Wikipedia

    en.wikipedia.org/wiki/Reed–Muller_code

    The Reed–Muller RM(r, m) code of order r and length N = 2 m is the code generated by v 0 and the wedge products of up to r of the v i, 1 ≤ i ≤ m (where by convention a wedge product of fewer than one vector is the identity for the operation).
