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.

- A degree of longitude is the 1-360th part of the great equatorial circle, or any circle parallel to it. a degree of latitude is the 90th part of the quadrant, or quarter of a great meridional circle. each degree is divided into 60 minutes, and each minute into 60 seconds, according to the sexagesimal division of the circle. also, rank or condition.

Degree day, английский
There are two types, heating-degree days and cooling-degree days, both reflecting the extent to which a daily temperature falls below or rises above an assumed base, usually 65 degrees fahrenheit (in the united states). temperature forecasts can assist in predicting energy consumption for heating and cooling.
