Quadratic attenuation, английский
The intensity of a beam of light that diminishes quickly at first then more slowly as it gets further from the light source.
Quadratic bezier curve, английский
A curve described by two endpoints and one control point.
Quadratic equation, английский
Квадратное управление
Quadratic form, английский
Квадратичная форма
Quadratic formula, английский
A formula giving the roots of a quadratic equation.
Quadratic programming, английский
- Квадратичное программирование
- Variant of linear programming in which the objective function is quadratic rather than linear. in portfolio selection, we often minimize the variance of the portfolio (which is a quadratic function) subject to constraints on the mean return of the portfolio.

Quadratic scoring rule, английский
See: brier scoring rule. quasi-bayesian theory bayesian methods for representing uncertainty in decision and inference problems assume that the uncertainty can be represented by a single probability distribution. however, in practice, it is often difficult to specify a single distribution for states of an attributes. this may be due to incomplete knowledge about the attributes or to an inability or lack of desire to specify a single distribution. quasi-bayesian theory offers a generalization of classical bayesian theory to encompass these situations, by allowing operations on a set of distributions. in particular, since it is concerned with linear operations on these distributions (e.g., average gains or losses), it works with convex sets of distributions. see also: lower expectation.

Spline, английский
- A spline is a mathematical function defined over a compact region of a (continuous) variables range. it is generally continuous and is often represented by a low order polynomial function (or its integral). the knots of a spline are its points of inflection. its degree is a measure of the number of continuous derivatives. these functions underlie many data mining and nonparametric or semi-parametric regression functions. since they are only defined over a region of the full attribute range, they allow the function to adapt well to data in their region of support without strongly influencing the results in regions outside that region. techniques such as classification and regression trees (cart) and c4.5 that recursively partition the attribute space can be thought of as recursive spline functions with zero-order splines (constant values) fit in each region. the attributes in each sub-region so defined can then be searched for further places to partition that region adaptively for improved prediction. see also: c4.5, classification and regression trees, multivariate adaptive regression spline, nonparametric. split-sample validation a method for estimating the error in automated modeling techniques such as neural networks, recursive partitioning, and data mining. the data are split into two parts, a larger part for estimation and a small hold out sample used to estimate the true error. the technique is best used when there is a very large amount of data available as it reduces the size of the training data.
- A curved line, made up of segments and defined by control points.
Spline insert, английский

Spline joint, английский
A joint formed by inserting a spline in a slot cut into the two butting members. split 1. a rupture in a built-up roof membrane, resulting from tensile stresses. 2. a crack that extends completely through a piece of wood or wood veneer. 3. a brick cut lengthwise, in two pieces, parallel to the wide face of the brick, so that it is half as thick; also called scone. spliced pile 922 spline, false tongue, feather, slip feather, slip tongue 1. a long thin strip of wood or spline, 1 splice plate spline, 2 split, 3
