Local regression
| Глоссарий по искусственному интеллекту |
Classical regression approaches assume that a particular structural relationship holds over the entire range of predictors. local regression techniques assume that (usually) simple structures hold around each case in the data space, but that data points` "interestingness" decline the further one goes from its area. local regressions can typically reproduce a classical regression approach when the global regularity holds and outperform it when the regularity does not hold. smoothing splines, neural networks and regression and classification trees are all forms of local regression. see also: machine learning. locally optimal searches (solutions) a locally optimal search algorithm will use an algorithm that can find the best one-step or two-step result but is not guaranteed to find the globally optimum solution. often improved results can be found by iterating the search or by adding random perturbations to a local solutions.

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

- Превосходить по своим эксплуатационным качествам; выполнять с улучшенными качествами
- In general, this means to do better than some particular benchmark. mutual fund xyz is said to outperform the s&p500 if its return exceeds the s&p500 return. however, this language does not take risk into account. that is, one might have a higher return than the benchmark in a particular year because of higher risk exposure. outperform is also a term used by analysts to describe the prospects of a particular company. usually, this means that the company will do better than its industry average. related: underperform.

- 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.
