  2. Rendezvous hashing - Wikipedia

    en.wikipedia.org/wiki/Rendezvous_hashing

    Clients C 1 and C 4 independently pick the same random subset of four sites {S 2, S 5, S 6, S 10} from among the twelve options S 1, S 2, ..., S 12, for placing replicas or shares of object O. Rendezvous or highest random weight (HRW) hashing [ 1 ] [ 2 ] is an algorithm that allows clients to achieve distributed agreement on a set of k ...

  3. Weighted majority algorithm (machine learning) - Wikipedia

    en.wikipedia.org/wiki/Weighted_majority...

    [1] [2] The algorithm assumes that we have no prior knowledge about the accuracy of the algorithms in the pool, but there are sufficient reasons to believe that one or more will perform well. Assume that the problem is a binary decision problem. To construct the compound algorithm, a positive weight is given to each of the algorithms in the pool.

  4. Simpson's rule - Wikipedia

    en.wikipedia.org/wiki/Simpson's_rule

    Composite Simpson's 3/8 rule is even less accurate. Integration by Simpson's 1/3 rule can be represented as a weighted average with 2/3 of the value coming from integration by the trapezoidal rule with step h and 1/3 of the value coming from integration by the rectangle rule with step 2h. The accuracy is governed by the second (2h step) term.

  5. Multiplicative weight update method - Wikipedia

    en.wikipedia.org/wiki/Multiplicative_Weight...

    The aim is to find non-negative weights such that for all examples, the sign of the weighted combination of the features matches its labels. That is, require that for all . Without loss of generality, assume the total weight is 1 so that they form a distribution.

  6. Weighted automaton - Wikipedia

    en.wikipedia.org/wiki/Weighted_automaton

    Hasse diagram of some classes of quantitative automata, ordered by expressiveness. [1]: Fig.1 In theoretical computer science and formal language theory, a weighted automaton or weighted finite-state machine is a generalization of a finite-state machine in which the edges have weights, for example real numbers or integers.

  7. Complex data type - Wikipedia

    en.wikipedia.org/wiki/Complex_data_type

    The Go programming language has built-in types complex64 (each component is 32-bit float) and complex128 (each component is 64-bit float). Imaginary number literals can be specified by appending an "i". The Perl core module Math::Complex provides support for complex numbers. Python provides the built-in complex type. Imaginary number literals ...

  8. Calculus on finite weighted graphs - Wikipedia

    en.wikipedia.org/wiki/Calculus_on_finite...

    Calculus on finite weighted graphs is used in a wide range of applications from different fields such as image processing, machine learning, and network analysis. A non-exhaustive list of tasks in which finite weighted graphs have been employed is: image denoising [2] [3] image segmentation [4] image inpainting [2] [5] tomographic ...

  9. Algorithms for calculating variance - Wikipedia

    en.wikipedia.org/wiki/Algorithms_for_calculating...

    This algorithm can easily be adapted to compute the variance of a finite population: simply divide by n instead of n − 1 on the last line.. Because SumSq and (Sum×Sum)/n can be very similar numbers, cancellation can lead to the precision of the result to be much less than the inherent precision of the floating-point arithmetic used to perform the computation.
