  2. Digital Signature Algorithm - Wikipedia

    en.wikipedia.org/wiki/Digital_Signature_Algorithm

    The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem. In a public-key cryptosystem, a pair of private and public keys are created: data encrypted with either key can ...

  3. Google Answers - Wikipedia

    en.wikipedia.org/wiki/Google_Answers

    Google Answers' predecessor was Google Questions and Answers, which was launched in June 2001. This service involved Google staffers answering questions by e-mail for a flat fee (US$3.00). It was fully functional for about 24 hours, after which it was shut down, possibly due to excessive demand and the tough competition that Yahoo! set in place ...

  4. MapReduce - Wikipedia

    en.wikipedia.org/wiki/MapReduce

    MapReduce is a programming model and an associated implementation for processing and generating big data sets with a parallel and distributed algorithm on a cluster. [1] [2] [3]A MapReduce program is composed of a map procedure, which performs filtering and sorting (such as sorting students by first name into queues, one queue for each name), and a reduce method, which performs a summary ...

  5. Digital subtraction angiography - Wikipedia

    en.wikipedia.org/wiki/Digital_subtraction...

    Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...

  6. Answer set programming - Wikipedia

    en.wikipedia.org/wiki/Answer_set_programming

    In ASP, search problems are reduced to computing stable models, and answer set solvers—programs for generating stable models—are used to perform search. The computational process employed in the design of many answer set solvers is an enhancement of the DPLL algorithm and, in principle, it always terminates (unlike Prolog query evaluation ...

  7. Word2vec - Wikipedia

    en.wikipedia.org/wiki/Word2vec

    Word2vec was created, patented, [7] and published in 2013 by a team of researchers led by Mikolov at Google over two papers. [ 1 ] [ 2 ] The original paper was rejected by reviewers for ICLR conference 2013.

  8. Knapsack problem - Wikipedia

    en.wikipedia.org/wiki/Knapsack_problem

    The most common problem being solved is the 0-1 knapsack problem, which restricts the number of copies of each kind of item to zero or one. Given a set of items numbered from 1 up to , each with a weight and a value , along with a maximum weight capacity ,

  9. Domain-specific architecture - Wikipedia

    en.wikipedia.org/wiki/Domain-specific_architecture

    A domain-specific architecture (DSA) is a programmable computer architecture specifically tailored to operate very efficiently within the confines of a given application domain. The term is often used in contrast to general-purpose architectures, such as CPUs , that are designed to operate on any computer program .
