Additive models
| Глоссарий по искусственному интеллекту |
A modeling technique that uses weighted linear sums of the possibly transformed input variables to predict the output variable, but does not include terms such as cross-products which depend on more than a single predictor variables. additive models are used in a number of machine learning systems, such as boosting, and in generalized additive models (gams). see also: boosting, generalized additive models. additivity and variance stabilization (avas) avas, an acronym for additivity and variance stabilization, is an modification of the ace technique for smooth regression models. it adds a variance stabilizing transform into the ace technique and thus eliminates many of ace`s difficulty in estimating a smooth relationship. see also: ace.

Additive color system, английский
- Система с аддитивным синтезом цвета
- The color system that uses light rather than pigment to create color. it is the system of digital media and computer screens. the additive primary colors are red, green, and blue and are often referred to by their initials rgb. it is called the additive color model because red, green and blue light are added together in various combinations to reproduce a broad array of colors.

- The action undertakes a country when it buys and sells its own currency to protect its exchange value. actions registered competitive traders undertake by on the nyse to meet the exchange requirement that 75% of their traded be stabilizing, meaning that sell orders follow a plus tick and buy orders a tick. actions a managing underwriter undertake so that the market price does not fall below the public offering price during the offering period.

Regression, английский
- Statistical technique used to evaluate relationships among variables (22).
- Регрессия
- 1. a stage where symptoms of a disease are disappearing and the person is getting better 2. (in psychiatry) the process of returning to a mental state which existed when the person was younger
- 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

Retrospective data analysis, английский
A modeling process that is designed to understand past trends or events. a common problem in data analysis or data mining is that the objective is to predict future events based on past events, but that data are all based on past events. a common solution is to cross-validate the analysis by using sampling, "hold one out" or bootstrap analyses. each of these techniques attempts to provide "new" data by only using part of the database by only using part of the data to form the data and then using the remainder to validate the model. see also: cross-validation, bootstrapping.
Pattern directed invocation, английский
A modification used in a procedural representation of a knowledge base. rather than explicitly writing the query, it is given as a goal, and a variety of procedures can be used to satisfy it using a method such as backtracking. this adds some of the flexibility available in a declarative knowledge base, at the expense of the control available in a pure procedural representation. see also: declarative representation, knowledge base, knowledge representation, procedural representation.
