  2. Factorial - Wikipedia

    en.wikipedia.org/wiki/Factorial

    [39] [40] The factorial number system is a mixed radix notation for numbers in which the place values of each digit are factorials. [ 41 ] Factorials are used extensively in probability theory , for instance in the Poisson distribution [ 42 ] and in the probabilities of random permutations . [ 43 ]

  3. Factorial number system - Wikipedia

    en.wikipedia.org/wiki/Factorial_number_system

    The factorial number system is sometimes defined with the 0! place omitted because it is always zero (sequence A007623 in the OEIS). In this article, a factorial number representation will be flagged by a subscript "!". In addition, some examples will have digits delimited by a colon. For example, 3:4:1:0:1:0! stands for

  6. Factor (programming language) - Wikipedia

    en.wikipedia.org/wiki/Factor_(programming_language)

    Certain basic parts of the language are implemented in C++ such as the garbage collector and certain primitives. Factor uses an image-based model, analogous to many Smalltalk implementations, where compiled code and data are stored in an image. [10] To compile a program, the program is loaded into an image and the image is saved.

  8. Factorial code - Wikipedia

    en.wikipedia.org/wiki/Factorial_code

    To create factorial codes, Horace Barlow and co-workers suggested to minimize the sum of the bit entropies of the code components of binary codes (1989). Jürgen Schmidhuber (1992) re-formulated the problem in terms of predictors and binary feature detectors , each receiving the raw data as an input.
