Belief chain
| Глоссарий по искусственному интеллекту |
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, 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 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 vector, английский
Доверительный вектор
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.
Chain, английский
- Unit of length equal to 66 feet (20).
- A system of interlinking pins, plates and rollers that transmits power from the front cranks to the rear wheel.
- Цепь
- Арка из воздушных петель
- When mountains, hills, lakes, and islands are linked together, or follow each other in succession, so that their whole length greatly exceeds their breadth, they form what is termed a chain. a measuring chain is divided into links, &c., made of stout wire, because line is apt to shrink on wet ground and give way. the chain measure is 66 feet.
- [1] a series of metal links (rings) passing through one another to form a flexible tie with high 67 chain tensile strength. [2] a group of related islands forming a more-or-less straight line (if the line is curved they form an arc).
- Цепь; мерная цепь ~ of holes линия [цепочка] отверстий ~ of locks многоступенчатый шлюз ~ of power plants каскад гэс ~ of triangulation звено [ряд, дуга] триангуляции band ~ стальная мерная лента (геодезиста); мерная цепь
- Группа людей, покупающих дома по цепочке один у другого
- Arrangement of microbial cells in form of a line
- A unit of linear measurement equaling 22 yards or 1/80 of a mile.
Chain, английский
Chain and sprocket drive, английский
Power transmission in which a roller chain engages with two or more toothed wheels or sprockets. used mainly on bicycles, motorcycles, and in engines as a drive from crankshaft to camshaft.
Chain arrester gear, английский
Аэродромная тормозная установка с тяжелой цепью
Chain base index, английский
For this type of index, a value in any specific time period is based on the value of the same entity in the preceding period. changes in values can be compared between sequential time periods. this differs from a fixed base index in which values in any period are based on the initial value. see: fixed base index, index number
Chain binders, английский
Yarns running in the warp direction on the back of a woven carpet which hold construction yarns together.
Chain block, английский
A combination of sheaves over which chains are arranged in the same manner as the rope in a block and tackle. also called chain hoist.
Chain block., английский
Chain bolt, английский
At the top of a door, a spring bolt which is actuated by a chain attached to it.
Predecessor, английский
- Предшествующее событие
- Предшественник
- An activity that occurs before another activity in a series. a predecessor can be, but is not always, a prerequisite.

Bayesian belief function, английский
A belief function that corresponds to an ordinary probability function is referred to as a bayesian belief function. in this case, all of the probability mass is assigned to singleton sets, and none is assigned directly to unions of the elements. see also: belief function.
Opm, английский
- A blackboard-based planning system. it attempts to plan sequences of tasks that satisfy conflicting goals and constraints. given a list of tasks, their dependencies, priorities and constraints, it attempts to find feasible solutions to the problem.
- Stands for "other people`s money," which refers to borrowed funds used to increase the return on invested capital.
- Operational position management (us)
- Office of personnel management - an agency of the u. s. government responsible for personnel administration of all federal employees.
- Operational planning manager
