  • Random element — The term random element was introduced by Maurice Frechet in 1948 to refer to a random variable that takes values in spaces more general than had previously been widely considered. Frechet commented that the development of probability theory and… …   Wikipedia

  • Random variable — A random variable is a rigorously defined mathematical entity used mainly to describe chance and probability in a mathematical way. The structure of random variables was developed and formalized to simplify the analysis of games of chance,… …   Wikipedia

  • Vector quantization — is a classical quantization technique from signal processing which allows the modeling of probability density functions by the distribution of prototype vectors. It was originally used for data compression. It works by dividing a large set of… …   Wikipedia

  • Random naive Bayes — extends the Naive Bayes classifier by adopting the random forest principles: random input selection (bagging, i.e. bootstrap aggregating) and random feature selection ( [Breiman, 2001] ). Naive Bayes classifier Naive Bayes is a probabilistic… …   Wikipedia

  • Random phase approximation — (RPA) is one of the most often used methods for describing the dynamic electronic response of systems. In RPA, electrons are assumed to respond only to the total electric potential V (r) which is the sum of the external perturbing potential V… …   Wikipedia

  • Vector (STL) — Vectors (or std::vector) are a C++ implementation of the dynamic array data structure. Their interface emulates the behavior of a C array (i.e., capable of fast random access) but with the additional ability to automatically resize itself when… …   Wikipedia

  • Random effects model — In statistics, a random effect(s) model, also called a variance components model is a kind of hierarchical linear model. It assumes that the data describe a hierarchy of different populations whose differences are constrained by the hierarchy. In …   Wikipedia

  • Random measure — In probability theory, a random measure is a measure valued random element.Kallenberg, O., Random Measures , 4th edition. Academic Press, New York, London; Akademie Verlag, Berlin (1986). ISBN 0 123 94960 2 [http://www.ams.org/mathscinet… …   Wikipedia

  • Vector soliton — Among all the soliton considered, the optical soliton draws the most attention as it is possible to generate ultrafast pulses and has wider application. optical soliton can be classified as two groups:temporal soliton and spatial soliton.however …   Wikipedia

  • Random walk — A random walk, sometimes denoted RW, is a mathematical formalization of a trajectory that consists of taking successive random steps. The results of random walk analysis have been applied to computer science, physics, ecology, economics and a… …   Wikipedia

  • Random graph — In mathematics, a random graph is a graph that is generated by some random process. The theory of random graphs lies at the intersection between graph theory and probability theory, and studies the properties of typical random graphs.Random graph …   Wikipedia
