Belief, английский
- Creencia
- A freely available program for the manipulation of graphical belief functions and graphical probability models. as such, it supports both belief and probabilistic manipulation of models. it also allows second-order models (hyper-distribution or meta-distribution). a commercial version is in development under the name of graphical-belief. see also: belief function, graphical model.
Belief about beliefs, английский
Представление о представлениях; убеждения относительно убеждений belief-invoked interpretation рассуждение на основе принятых убеждений; интерпретация от фактов; вывод снизу вверх
Belief chain, английский
A belief net whose directed acyclic graph (dag) can be ordered as in a list, so that each node has one predecessor, except for the first which has no predecessor, and one successor, except for the last which has no successor (see figure b.1.). figure b.1 —
Belief change flexibility, английский
The ability to try out new beliefs for a short time to test their usefulness.
Belief core, английский
The core of a set in the dempster-shafer theory is that probability is directly assigned to a set but not to any of its subsets. the core of a belief function is the union of all the sets in the frame of discernment which have a non-zero core (also known as the focal elements). suppose our belief that one of fred, tom, or paul was responsible for an event is 0.75, while the individual beliefs were b(fred)=.10, b(tom)=.25, and b(paul)=.30. then the uncommitted belief would be 0.75- (0.1+0.25+0.30) = .10. this would be the core of the set {fred, tom, paul}. see also: belief function, communality number.
Belief function, английский
In the dempster-shafer theory, the probability certainly assigned to a set of propositions is referred to as the belief for that set. it is a lower probability for the set. the upper probability for the set is the probability assigned to sets containing the elements of the set of interest and is the complement of the belief function for the complement of the set of interest (i.e., pu(a)=1 -bel(not a).) the belief function is that function which returns the lower probability of a set. belief functions that can be compared by considering that the probabilities assigned to some repeatable event are a statement about the average frequency of that event. a belief function and upper probability only specify upper and lower bounds on the average frequency of that event. the probability addresses the uncertainty of the event, but is precise about the averages, while the belief function includes both uncertainty and imprecision about the average. see also: dempster-shafer theory, quasi-bayesian theory.
Belief net, английский
Used in probabilistic expert systems to represent relationships among variables, a belief net is a directed acyclic graph (dag) with variables as nodes, along with conditionals for each arc entering a node. the attribute(s) at the node are the head of the conditionals, and the attributes with arcs entering the node are the tails. these graphs are also referred to as bayesian networks (bn) or graphical models. see also: bayesian network, graphical model.
Belief revision, английский
Belief revision is the process of modifying an existing knowledge base to account for new information. when the new information is consistent with the old information, the process is usually straightforward. when it contradicts existing information, the belief (knowledge) structure has to be revised to eliminate contradictions. some methods include expansion which adds new ``rules" to the database, contraction which eliminates contradictions by removing rules from the database, and revision which maintains existing rules by changing them to adapt to the new information. see also: nonmonotone logic.
Belief system, английский
Sistema de creencias
Belief, faith; doctrine, английский
Beliefs, английский
- N pl псхл. убеждения benefactive и beneficiary
- Statements we think are true but cannot (or have not bothered to) check. see ‘logical levels’.
- Robert dilts defined beliefs as: closely held generalisations about (1) cause, (2) meaning, (3) boundaries in a) the world around us b) our behaviour c) our capabilities, and d) our identities.
Vector, английский
- An insect or animal which carries a disease and can pass it to humans the tsetse fly is a vector of sleeping sickness.
- Вектор
- Переносчик (возбудителя инфекции)
- [1] a straight line graphically representing the direction and magnitude of a force or movement. [2] to follow a designated compass direction to an amphibious landing beach. [3] to give an aircraft directions for its approach to set down on a flight deck or runway.
- Hard vector
- In computer graphics, a line drawn in a certain direction from a starting point to an endpoint, both of whose locations are identified by the computer using x-ycoordinates on a grid. vectors are used in the output of some graphics programs instead of groups of dots (on paper) or pixels (on screen).
- Animal (typically an arthropod) that transmits a pathogen from one host to another host; dna molecules that carry dna fragments from one organism to another
- Математический объект, обладающий направлением и длиной, но не имеющий определенного положения в пространстве.

Vector artwork, английский
An image generated from a mathematical description that determines the position, length, and direction in which lines are drawn. a vector graphic is created as a collection of lines rather than as a pattern of individual dots or pixels.
