Kohonen network
| Глоссарий по искусственному интеллекту |
A kohonen network is a form of unsupervised learning in neural networks and is similar to a k-means cluster analysis. each of the hidden units acts as a cluster center and the error measure is the sum of square differences between the input data and the nearest cluster center. the clusters compete with each other for the right to respond to an input pattern. there are several types of kohonen networks, including vector quantization, som (self-organizing maps), and learning vector quantization. see also: kolmogorov`s axioms the russian mathematician kolmogorov provided an axiomatic basis for probability. given a space of events s, and two subsets a and b of s, a function p() is a probability if p(a) > 0 p(s) = 1 if a b = 0, then p(a b) = p(a) + p(b). the three conditions are also referred to as positivity, normalization, and finite additivity. a slightly different form of the axioms substitutes countable additivity for the latter, allowing for countable collections of sets. see also: probability.

- [1] a group of radio stations sharing the same frequency. [2] interconnected computer systems. network-centric: this is a doctrine made possible by the information age and related to the revolution in military affairs debate. as defined by the pentagon in its report to congress: it involves new ways of thinking about how we accomplish our missions, how we organize and interrelate, and how we acquire and field the systems that support us.... this monumental task will span a quarter century or more. it will involve ways of operating that have yet to be conceived, and will employ technologies yet to be invented ... (and) has the potential to increase warfighting capabilities by orders of magnitude. the concept treats geographically dispersed platforms not as individual weapons, but as components in a vast network that allows messages and data to be exchanged between tactical elements without having to be passed up and down the chain of command. being inter-connected via high-speed satellite communication networks to form a global inter-service information grid, data will be centrally collated to create a coherent overall picture of the battlefield instantly available to all units, giving each of them enhanced situation awareness and enabling more rapid, more informed, and more effective decision-making (but see author’s comment under mission command).

Probability, английский
- Probability can be generally defined as a measure of how likely some event will occur. the event could be an explosion, a lottery win or perhaps cancer induction. mathematically speaking, the value of probability varies between 0 and 1 where 0 means an ev
- Вероятность. возможность.
- The probability of an event is a number between zero and 100%. the meaning (interpretation) of probability is the subject of theories of probability, which differ in their interpretations. however, any rule for assigning probabilities to events has to satisfy the axioms of probability.
- Вероятность
- Вероятность probability sample, syn. random sample
- Вероятность. мера случайности появления конкретного события. например, вероятность случайного выбора из популяции человека с конкретным качеством соответствует доле людей в популяции, обладающих этим качеством.
- Вероятность; возможность
- Вероятность; обеспеченность (гидрологической величины) ~ of no-failure вероятность безотказной работы
- Probability is a method for representing uncertainty about propositions or events. it represents the uncertainty about a proposition on a scale from 0 to 1, with a 0 representing complete certainty that the proposition is false or an event will not occur and a value of one will represent the opposite. formally, a probability measure is one that follows kolmogorov`s axioms. there are two main schools of thought on the meaning of probability. frequentists take a narrow interpretation of probability allowing only hypothetically repeatable events or experiments as being quantifiable by probability, while bayesians take a broader interpretation that allows reasoning about "one-shot" events and propositions based on the current knowledge about nature. the bayesian interpretation is most commonly used in artificial intelligence, while the frequentist interpretation is most commonly taught in statistics courses. the label "bayesian" arises from the central role that the bayes theorem plays in this use of probability. it allows one to reason from effects to causes and encourages the use of probability measures to describe supposedly fixed events or propositions which frequentists disallow. the probability for these events reflects one`s state of knowledge about the event, rather than being an assertion that the unknown event can vary. for example, a bayesian would have no qualms about making statements about the probability that a given die, rolled and hidden from his sight is, for example, a six. a frequentist would be unable to make such a statement, preferring to talk about his confidence in the method when applied to a hypothetically large number of repeated experiments. in the end, they would act in similar ways. when the long run data are available, bayesians and frequentists end up with the same estimates. see also: bayes theorem, kolmogorov`s axioms.
- Вероятность. математическое измерение возможности появления неко-его события, выраженное в виде дроби или процента [30]. значения статистической вероятности лежат в пределах от 1 или 100 процентов (всегда) до 0 или 0 процентов (никогда) [20]. наибольшее приближение к истинной вероятности дает относитель-ная частота события, полученная на основе большой серии измерений или результа-тов [33]. вероятность может быть также определена как выражение в некоторой неопределимой форме "степени уверенности" или как предельная частота события в бесконечной случайной последовательности [49].

Normalization, английский
- N нормализа- ция nostratic a ностратический hypothesis
- Usually refers to the process of dividing a data set by the square root of its sum of squares, so that the data set has a length of one. in reference to probability scores, normalization usually refers to the process of dividing the scores by their sum, so that the total of the scores becomes one. in the context of neural networks, normalization refers to the process of rescaling a vector to the (0, 1) range.
