Dependency models
| Глоссарий по искусственному интеллекту |
A statistical technique used in data mining and similar areas to describe the interrelationships between a set of measurements. unlike regression techniques, which treat one group of variables (the dependent or output variables) differently from another set (the independent or input variables), dependency modeling tends to treat all variables as being interrelated, although the methods does support directed relationships. the models can be thought of on two levels, a structural model and a quantitative model. at the structural level, the model specifies which variables are directly or locally interrelated with one another, often via a dependency graph (as illustrated below) or by a transition matrix. at the quantitative level a numeric value is assigned to each of the linkages allowed in the structural model. one such measure for a pair of continuous measurements might be partial correlation between the two variables, given all the other variables. the structural graph shown in figure d.2 illustrates the relationships among five variables: a, b, c, d, and e. in this example, the variable c is affected by all the remaining variables. variables a and b are related to each other and to c, but conditional on controlling c are unaffected by d and e. similarly, d and e are related to each other and to c, but,

- Statistical technique used to evaluate relationships among variables (22).
- Регрессия

- 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.

Correlation, английский
- A measure of linear association between two (ordered) lists. two variables can be strongly correlated without having any causal relationship, and two variables can have a causal relationship and yet be uncorrelated.
- Соотношение; корреляция
- N корреляция, соответ- ствие regular ~s закономерные соответствия
- Корреляция
- Correlation is a statistical measure of the association between two attributes or types of events. it typically ranges from -1 to 1, with a -1 indicating a complete negative association (e.g., if one type of event occurs the other cannot), and a +1 indicating a complete posipage 66 tive association. for continuous attributes, the pearson correlation coefficient is computed as the ratio of the covariance between two attributes to the product of the attributes` standard errors. see also: covariance.
- To correlate, in a stratigraphic sense, is to show correspondence in character and in stratigraphic position between geographically separated stratigraphic sections or rock bodies. there are different kinds of correlation depending on the feature or property to be emphasized (see section 3.a.9 and lithocorrelation, biocorrelation, and chronocorrelation). coset. a sedimentary unit made up o f two or more sets, either o f strata or o f cross-strata, separated from other strata or cross-strata by original flat surfaces o f erosion, nondeposition, or abrupt change in character (mckee and weir, 1953, p. 384).
- Creating relationships between an email activity and other records by using the information from email headers.
- Statistical measure of the degree to which the movements of two variables (stock/option/convertible prices or returns) are related. see: correlation coefficient.
- The extent to which a relationship exists between two or more elements. often used in seo research to infer relationships of variables on search rankings due to the black box nature of algorithms. always remember, however, that correlation ≠ causation.
- A standardised measure, bounded between −1 and +1, of the strength of association between two variables.

Statistics oracle, английский
A statistics oracle is a function that returns an approximation to the correct probability that a specified statistical query is true. the approximation is within a specified tolerance e of the true probability. the statistics oracle needs to be defined for a concept class and a distribution over the instance space. the oracle may be operating samples from a large database or on a noisy source of data. see also: statistical query.
