  2. Scale factor (computer science) - Wikipedia

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

    A scale factor of 1 ⁄ 10 cannot be used here, because scaling 160 by 1 ⁄ 10 gives 16, which is greater than the greatest value that can be stored in this fixed-point format. However, 1 ⁄ 11 will work as a scale factor, because the maximum scaled value, 160 ⁄ 11 = 14. 54, fits within this range. Given this set:

  3. Fixed-point arithmetic - Wikipedia

    en.wikipedia.org/wiki/Fixed-point_arithmetic

    A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable as the integer value 1230 with implicit scaling factor of 1/1000 (meaning that the last 3 decimal digits are implicitly assumed to be a decimal fraction), and the value 1 230 000 can be represented ...

    As a power of ten, the scaling factor is then indicated separately at the end of the number. For example, the orbital period of Jupiter's moon Io is 152,853.5047 seconds, a value that would be represented in standard-form scientific notation as 1.528535047 × 10 5 seconds. Floating-point representation is similar in concept to scientific notation.

  5. Binary number - Wikipedia

    en.wikipedia.org/wiki/Binary_number

    The base-2 numeral system is a positional notation with a radix of 2.Each digit is referred to as bit, or binary digit.Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because of ...

  6. Binary prefix - Wikipedia

    en.wikipedia.org/wiki/Binary_prefix

    A binary prefix is a unit prefix that indicates a multiple of a unit of measurement by an integer power of two. The most commonly used binary prefixes are kibi (symbol Ki, meaning 2 10 = 1024 ), mebi ( Mi, 2 20 = 1 048 576 ), and gibi ( Gi, 2 30 = 1 073 741 824 ).

  7. Evaluation of binary classifiers - Wikipedia

    en.wikipedia.org/wiki/Evaluation_of_binary...

    Generally these statistics will be scale invariant (scaling all the numbers by the same factor does not change the output), to make them independent of population size, which is achieved by using ratios of homogeneous functions, most simply homogeneous linear or homogeneous quadratic functions. Say we test some people for the presence of a disease.

  8. BUFR - Wikipedia

    en.wikipedia.org/wiki/BUFR

    The addition of new element descriptors in Table B does not require changes to the BUFR software specification. The Table B definition of an element descriptor includes its number, short text definition, decoding parameters (bit width, scale factor, and bias), and type (numerical, character string, code table, etc.).

  9. Mixed-precision arithmetic - Wikipedia

    en.wikipedia.org/wiki/Mixed-precision_arithmetic

    PyTorch AMP uses exponential backoff to automatically adjust the scale factor for loss scaling. That is, it periodically increase the scale factor. That is, it periodically increase the scale factor. Whenever the gradients contain a NaN (indicating overflow), the weight update is skipped, and the scale factor is decreased.
