Adaboost
| Глоссарий по искусственному интеллекту |
Adaboost is a recently developed method for improving machine learning techniques. it can dramatically improve the performance of classification techniques (e.g., decision trees). it works by repeatedly applying the method to the data, evaluating the results, and then reweighting the observations to give greater credit to the cases that were misclassified. the final classifier uses all of the intermediate classifiers to classify an observation by a majority vote of the individual classifiers. it also has the interesting property that the generalization error (i.e., the error in a test set) can continue to decrease even after the error in the training set has stopped decreasing or reached 0. the technique is still under active development and investigation (as of 1998). see also: arcing, bootstrap aggregation (bagging). adaboost.mh adaboost.mh is an extension of the adaboost algorithm that handles multi-class and multi-label data. see also: multi-class, multi-label.

- 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.

- Term used to denote the adding together of the taxpayer`s income from all sources in order to determine the applicable tax rate for income tax purposes.
- A process by which the properties of a collection are described in terms of the sums of the properties of the units contained in that collection. the most elementary aggregative procedure is counting and a frequency so obtained represents the properties of a set by number rather than by the list of elements it contains. aggregation gives rise to macro theories of micro processes and yields measures and insights not demonstrable by means of the units aggregated thereby. e.g., the statement "the average family has 2.5 children" describes the property of an aggregate, not of a real family. the correlation coefficient is also a measure that aggregates numerous observations neither is capable of demonstrating that relation by itself. quantum physics, economics and the social sciences are most successful in describing their objects as aggregates. aggregation is justifiable whenever units are sufficiently independent and similar, e.g., in expressing political opinions through voting or market preferences through individual purchases. aggregation leads to misleading indicators and theories whenever the whole collection exhibits an organization not expressed in a mere summation (->system, ->externalities). in econometrics, that difference is represented in so-called interaction effects.
- A collection of objects that makes a whole. an aggregation can be a concrete or conceptual set of whole-part relationships among objects.
- A collection of shared objects.
- A table or structure containing pre-calculated data for an online analytical processing (olap) cube. aggregations support the rapid and efficient querying of a multidimensional database.

- A collection of individual units or particles gathered together into a mass or body.

Virtual attribute, английский
A virtual attribute is one whose values are not observed or counted but are computed from other attributes. they are often computed as proxies for concepts or to simplify analysis. as an example of concept proxies, other models might suggest that a particular function of observable attributes represents the wealth of a person, and the wealth function can be computed for all cases in the database for later analysis by, say, a data mining algorithm looking for purchase patterns. an example of the latter would be the collapse of the discrete attribute containing years of schooling into a nominal variable with a small number of categories. see also: knowledge discovery in databases, machine learning. virtual reality modeling language (vrml) vrml is a language used to store the specifications of a three-dimensional space. the vrml description of a scene would be used by, for example, a world wide web (www) browser to render the scene and to change the image or perform other actions in reaction to a person`s input.
Ade monitor, английский
