Clustering
| Глоссарий по эконометрике (англо-русский) |
- The tendency e.g. of laser-active ions in laser gain media to form clusters in their host medium
- Кластеризация; выделение кластеров; объединение в кластеры; группирование
- Clustering is a technique used in data mining, online analytical processing (olap), and similar activities to group observations. a clustering procedure attempts to identify and extract "similar" groups of observations from a data set. unlike classification procedures, the number and memberships in the groups are not known a priori. the observations are grouped on the same set of attributes as is used to assess their homogeneity. in contrast, classification and regression techniques use one group of variables to obtain homogeneity on a second set. the clustering process can either be agglomerative, where each record starts as its own cluster and is merged with other clusters, or divisive, where all the data starts in a single large cluster and is gradually broken down into smaller, more homogeneous clusters. while the clustering is often of interest in its own right, it can also be used to pick out interesting subgroups for further analysis. the clusters can be disjoint, so that each observation falls in one and only one cluster, hierarchical, where the higher level clusters are further split into sub-clusters recursively, or overlapping, so that an individual data point can have membership into more than one cluster. see also: classification procedures, data mining, knowledge discovery in databases, regression.
- A data mining technique that analyzes data to group records together according to their location within the multidimensional attribute space.
- The grouping of multiple servers in a way that allows them to appear to be a single unit to client computers on a network. clustering is a means of increasing network capacity, providing live backup in case one of the servers fails, and improving data security.

- Структура логики. в психологию это понятие ввел в 1937 г. ж. пиаже в качестве одного из основных понятий своей концепции интеллекта операциональной. группировка считается связующим звеном между логическими и психологическими структурами. в формально-логическом плане группировка – это закрытая, обратимая система, где все операции подчиняются пяти формальным критериям:
- Распределение изучаемой совокупности объектов анализа на однородные группы по заданным признакам. цель группировки выделение однородных групп объектов анализа по интересующим исследовател
Кластеризация, русский
- Реализация объединения машин, представляющегося единым целым для операционной системы, системного программного обеспечения, прикладных программ и пользователей.
- Способ разбиения объектов или явлений на классы на основании некоторого отношения близости в пространстве признаков. см. также таксономия, классификация.

- The placement of an item under the correct number in the customs tariff for duty purposes. at times this procedure becomes highly complicated; it is not uncommon for importers to resort to litigation over the correct duty to be assessed by the customs on a given item
- Классификация; категоризация; сортировка
- The process of assigning a set of records from a database (observations in a dataset) into (usually) one of ``small" number of pre-specified disjoint categories. related techniques include regression, which predicts a range of values and clustering, which (typically) allows the categories to form themselves. the classification can be "fuzzy" in several senses of the word. in usual sense, the classification technique can allow a single record to belong to multiple (disjoint) categories with a probability (estimated) of being in each class. the categories can also overlap when they are developed either through a hierarchical model or through an agglomerative technique. finally, the classification can be fuzzy in the sense of using "fuzzy logic" techniques. see also: clustering, fuzzy logic, regression. classification and regression trees (cart) classification and regression trees (cart) is a particular form of decision tree used in data mining and statistics.

- Regression commonly refers to the process of developing an empirical (data-driven) model to predict and/or explain one or more attributes in a database or set of data. it is most frequently associated with the simple linear model (y=mx+b) taught in most introductory statistics courses; the same ideas have been extended in many directions, including classification problems. when the emphasis is on hypothesis testing and simple models, the regression output is typically a few parameters that provide a direct linkage from the input variables to the predicted variables (or classification). in other situations the emphasis is on explaining as much of the variability in the output variables as is "reasonable" from the input variables. in this case, there are a number of "advanced" techniques, such as smoothing splines, decision trees, neural nets, and so forth, for which there are many "free" parameters. the meaning of any one of these parameters can be obscure. many data mining techniques are, at their core, variations on well-known regression techniques. see also: classification, clustering, decision trees, neural nets.
- The reappearance of a previously fixed problem.
- The statistical process of predicting one or more continuous variables, such as profit or loss, based on other attributes in the dataset.
- A mathematical technique used to explain and/or predict. the general form is y = a + bx + u, where y is the variable that we are trying to predict; x is the variable that we are using to predict y, a is the intercept; b is the slope, and u is the regression residual. the a and b are chosen in a way to minimize the squared sum of the residuals. the ability to fit or explain is measured by the r-square.
- A seaward retreat of a shoreline, generally expressed as a seaward
