Concept learning
| Глоссарий по искусственному интеллекту |
In machine learning, a concept is exemplified by a set of positive examples (cases that are examples of the concept) and a set of negative examples (cases that are not examples of the concept). in concept learning, the learner is attempting to construct a rule or algorithm that allows it to completely separate the positive and negative examples. see also: equivalence query, machine learning, membership query.

Concept, английский
- A thought or idea, or something which someone might be able to imagine
- N 1 концепт, понятие (син. figure of thought, trope); 2 теория untranslatability basic ~ корневое понятие conceptual 31 consonant concrete ~ конкретное понятие derivational ~ деривационное понятие mixed-relational ~ смешанно-реляционное понятие pure-relational ~ чисто-реляционное понятие relational ~ связанное, реляционное понятие concrete ~ ~ конкретное реляционное по- нятие
- Понятие; концепция; решение, замысел ~ of form and space концепция (архитектурных) форм и пространства
- A symbol with meaning or interpretation in an application domain. see also: extension of a concept, intension of a concept.
- The cognitive meaning of a term and the smallest unit of (conscious) thought processes. concepts are neither true nor false but more or less applicable (a) to recognize an object as an instance of the concept, (->recognition) (b) to produce or to understand sentences in which the concept is expressed and (c) to develop constructs or cognitive systems using the concept in question. regarding (a) concepts provide decision rules for determining class membership rather than extensional membership lists. e.g., the concept "tv commercial" specifies certain defining features which when present identify a sequence of tv images as an instant of the concept without prior knowledge of its class membership (->connotation).
- A unit of thought that consists of characteristics attributed to an object, a relation, or an entity and that can be expressed in a symbol (e.g., a word or phrase).
- An idea or design.
Concept checking question, английский
A display question intended to ascertain whether an idea has been understood.
Concept classification, английский
Смысловая классификация; смысловая сортировка
Concept clearance, английский
Утверждение концепции проекта
Concept coordination, английский
Координатное индексирование
Concept definition, английский
Определение понятия
Concept drift, английский
Systems that classify or predict a concept (e.g., credit ratings or computer intrusion monitors) over time can suffer performance loss when the concept they are tracking changes. this is referred to as concept drift. this
Concept formulation, английский
- Формулирование концепции [основного принципа]
- Формулирование понятий
Concept formulation phase, английский
Этап разработки концепции
Concept freeze, английский
Concept generalization, английский
Обобщение понятия
Concept language, английский
A language used to construct concepts, such as a first-order or propositional language. the choice of language determines the concepts that are expressible in a particular system. see also: concept, concept space, knowledge discovery in databases.
Concept lattice, английский
A concept space that is partially ordered by the concept`s extensions and intensions forms a concept lattice. extensions are related by a subset relation among concepts and by the greater generality of the concept intensions. the orderings are only partial as not all subsets or clusters will satisfy a less than or greater than relationship. two subsets may both contain a given subset and be contained in another subset but not have any ordering between themselves, or they may share nothing more that the empty set as a subset and the universe as a superset. see also: partially ordered set.
Concept of the invention, английский
- Идея изобретения; сущность изобретения
- Идея изобретения; существо изобретения
Concept plan, английский
A plan, 1 illustrating the assessment and possible suitable development of a site.
Concept space, английский
Consider the set of all concepts that can be formed with a particular language and attribute set. if these concepts can be ordered or partially ordered, they form a concept space. see also: concept language, concept lattice.
Concept testing, английский
Проверка концепций. исследование, главной задачей которого является проверка идеи или концепции. проверка концепции осуществляется для оценки вероятности того, что маркетинговые мероприятия достигнут запланированных целей. производители до вложения значительных инвестиций в развитие производства используют проверку концепций для разведочного исследования рекламы, продукта и цен.
Concept verification test (program), английский
Программа исследования принципа размещения оборудования в отсеке космической станции «спейслэб»
Conceptacle, английский
Conceptaculum [i, n], латинский
Completely, английский
Вполне; полностью; совершенно
Equivalence, английский
- N эквивалентность dynamic ~ динамическая эквивалентность level of ~ уровень эквивалентности: pragmatic ~ ~ прагматический situational ~ ~ ситуационный transformational ~ трансформационный уро- вень эквивалентности
- Эквивалентность. в отношении лекарственных средств выделяют фармацевтическую (химическую) эквивалентность (см. pharmaceutical equivalence), биологическую эквивалентность (см. bioequivalence) и терапевтическую эквивалентность (см. therapeutic equivalence). встречающиеся термины: равнозначность, равноценность, взаимозаменяемость.
Membership, английский
- A relationship of being a member of an organization, such as a gym or club.
- In asp.net, an application feature that manages a store of user credentials for a web site. membership can be integrated with login controls or other asp.net authentication features to provide login security for your site.

Equivalence query, английский
In machine learning the learning program sometimes needs to test the validity of a rule with an external teacher, such as asking "are all winged animals birds?" this type of question is called an equivalence query, as it is asking if the concept of birds is equivalent to the rule "winged animals are birds." see also: concept learning, machine learning, membership query.
Membership query, английский
In machine learning, the learner sometimes needs to query an external source to ask questions of a "teacher." when it asks a question such as "is a robin a bird" while trying to learn the concept of bird, it is performing a membership query. see also: concept learning, equivalence query, machine learning. merge-purge a knowledge discovery in databases-based (kdd-based) system developed in the mid-1990s to identify duplicate records in large databases. it has been successfully applied to the identification of duplicate welfare claims in data from the welfare department of the state of washington. see also: knowledge discovery in databases. merge/purge problem in knowledge discovery in databases (kdd) and data warehousing, a common problem involves the merging of multiple large databases from different sources, with different representations. the data has to be cleaned and joined into a single homogeneous whole before the kdd process can begin. this important process is known by several names, including the merge/purge problem, record linkage, instance identification, semantic integration, and data cleansing.
