- Windowing is a term that can have multiple meanings in a machine learning context. it has been used in the id3 and c4.5 context to refer to the process of selecting a sub-sample of the original data and developing a model. the model is tested against the remaining data, and, if its performance is not satisfactory, a portion of the test data "failures" are included with the original sub-sample and the model refit. this selection procedure can be repeated until the model fits well enough. the effectiveness of this technique depends on the domain and the data. an alternative use of the same term is in time series and techniques derived from ``local" models (e.g., smoothing regression models). in this context, the window describes an area around the prediction point, and only cases that fall within that window are used to make the local prediction. these windows often differentially weight the observations within the window so that observations that are "close" to the target are weighted more heavily than those that are "far away." the size of the window can be chosen by resampling techniques such as cross-validation.

- 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.

- Forecasting quantitative or qualitative outputs through function approximation, applied on input data or measurements.59 610 p t echn i cal g los sary
- Literally knowing something outside the range of an observer`s experiences. minimally, prediction is a mere extrapolation of given data into the future (forecasting) or into the past (retrodiction) (->estimation). it is usually justified by reference to general theories or models which serve as the basis for drawing inferences from available data to phenomena outside their range. thus, predictions are the conclusions drawn from the premise of available data using theories and models as a kind of syllogistic device (->simulation) •
- A data mining technique that analyzes existing data and uses the results to predict values of attributes for new records or missing attributes in existing records. for example, existing credit application data can be used to predict the credit risk for a new application.
