Unsupervised learning
| Глоссарий по искусственному интеллекту |
The goal of unsupervised learning is for a computer to process a set of data and extract a structure which is relevant to the problem at hand. this can take different forms. in cluster analysis and some forms of density estimation, the goal is to find a small number "groups" of observations which have a simple structure. graphical and other forms of dependency models reduce the interrelations between the variables to a smaller number. in neural networks, unsupervised learning is a form of cluster analysis or density estimation, where the network is being trained to reproduce the input. it is also referred to as auto-association. prominent techniques include kohonen networks and hebbian learning. see also: supervised learning.

Learning, английский
- A condition that results in someone finding it difficult to learn skills or information at the same rate as others of similar age children with learning disabilities
- The act of gaining knowledge of something or of how to do something
- N изучение language ~ изучение языка: computer assisted ~ компьютеризирован- ное, при помощи компьютера
- Fitting a model to data.
- A process of growing success in a fixed environment. e.g., mastering the violin, aquiring linguistic skills, increasing the accuracy of guesses, driving safer (ackoff). thus learning is not the same as aquiring knowledge through reception of information even though this often preceeds manifest improvements. learning is also different from problem solving which involves making decisions of how to bridge the gap between a present and a desired state and adaptation which implies changes in response to a changing environment not necessarily of growing success. it is only when behavior noticeably increases the efficiency with which information is processed, desirable states are reached, errors are avoided, or a portion of the world is controlled can one speak of learning. consciousness mayor may not be involved. learning by trial and error is a process by which feedback on errors prevents unsuccessful behavior from reoccuring thus increasing success. liee~
- The purposeful acquisition of knowledge. in language terms, this is sometimes contrasted with acquisition which refers to the more-or-less unconscious picking up of a language through exposure to meaningful input.

- Расчет; количественная оценка; вычисление
- The process of generating a score or scoring function for a dataset. this can refer to either the process of fitting the model where you would be estimating the coefficients of the equations (e.g., the parameters of a regression function or the split points in a decision tree) or the process of assigning scores to individual observations using the model (e.g., credit ratings). this usually refers to a prediction or scoring function, as opposed to a classification function, but can also be used in the latter context. see also: classification, statistics.

Association, английский
- Ассоциация, объединение, союз
- Two variables are associated if some of the variability of one can be accounted for by the other. in a scatterplot of the two variables, if the scatter in the values of the variable plotted on the vertical axis is smaller in narrow ranges of the variable plotted on the horizontal axis (i.e., in vertical "slices") than it is overall, the two variables are associated. the correlation coefficient is a measure of linear association, which is a special case of association in which large values of one variable tend to occur with large values of the other, and small values of one tend to occur with small values of the other (positive association), or in which large values of one tend to occur with small values of the other, and vice versa (negative association).

- In psychology, the cognitive connection between two or more concepts or ideas such that the presence of one tends to evoke the others. in sociology, the process by which people become allied to one another and form groups as the result of such alliances. in statistics, the cooccurance of two or more events with a probability above what would be expected by chance. dissociation is the logical complement of the statistical concept of association.

- The mapping of a file extension (for example, .mp3) or protocol (for example, http) to a programmatic identifier (progid). this mapping is stored in the registry as a per-user setting with a per-computer fallback. applications that participate in the default programs system set the association mapping for the file extension or protocol to point to the progid keys that they own.
- The state of being totally connected to, or experiencing, an event, mental or external. the opposite is dissociation (sometimes, disassociation), which is being an objective observer.

Generalized upper model, английский
The generalized upper model is a task-independent and domain-independent ontology that supports natural language processing in english, german, and italian. it contains a hierarchy of about 250 concepts and a separate hierarchy for relationships. see also: ontology, http://www.darmstadt.gmd.de/publish/komet/genum/newum.html general problem solving (gps) inference engine gps sought a series of operations that would eliminate the difference between an initial state and a final goal. it used a means-ends analysis to determine the individual steps. newell, shaw, and simon developed the gps inference engine. see also: means-ends analysis. general regression neural network (grnn) a general regression neural network (grnn) is the continuous analog of donald specht`s probabilistic neural networks (pnn). rather than return a 0-1 signal from each hidden unit that the input case matches, it
Grand tour, английский
The grand tour is a name for data mining and visualization techniques that are used to explore highdimensional data spaces. the data are projected onto a series of two-dimensional and three-dimensional plots, along with measures of interest. the tour can be random or can be directed toward finding projections that are "interesting" to the analyst directing the tour. an example could be the exploration of purchase data patterns to reveal unexpected associations.
