Random field — A random field is a generalization of a stochastic process such that the underlying parameter need no longer be a simple real, but can instead be a multidimensional vector space or even a manifold.At its most basic, discrete case, a random field… … Wikipedia
Markov random field — A Markov random field, Markov network or undirected graphical model is a set of variables having a Markov property described by an undirected graph. A Markov random field is similar to a Bayesian network in its representation of dependencies. It… … Wikipedia
Conditional random field — A conditional random field (CRF) is a statistical modelling method often applied in pattern recognition. More specifically it is a type of discriminative undirected probabilistic graphical model. It is used to encode known relationships between… … Wikipedia
Conditional Random Field — Ein Conditional Random Field (CRF) ist ein ungerichtetes graphisches Modell. Oft werden CRFs zum Taggen von sequentiellen Daten verwendet. Das bedeutet, das CRF erhält eine Sequenz X als Eingabe und gibt eine gleichlange Sequenz Y aus. Im… … Deutsch Wikipedia
