weight function

[′wāt ‚fəŋk·shən]
(mathematics)
Two real valued functions ƒ and g are orthogonal relative to a weight function σ on an interval if the integral over the interval of ƒ· g ·σ vanishes.
A function defined on the edges of a network or the arcs of a directed network, whose value at each edge or arc is the unique nonnegative integer assigned to that edge or arc.
A function defined on the vertices of a generalized s-t network, whose value at each vertex is a nonnegative integer.

The new weighting function for Eq 12 is now given by:
This paper is concerned solely with a weighting function for soil hydraulic limitations in the 'dry range', which arise partly from the declining ability of the soil matrix to release water and partly from its declining ability to transport that water within the rhizosphere under hydraulic gradients.
Any correlation between CCT and optical safety, material safety and photobiological safety exists because CCT calculations also include a weighting function covering the blue-light region; so if the proportion of blue light (and any associated risk) changes, so too does the CCT.
To aggregate the different estimates, an add and weighting function B(K) determines the weight contribution of central pixel to its neighbor at relative position K:
Applying the global weighting functions none, normal, and GfIdf, resulted in lower precision regardless of the corpus text and local weighting function applied, and the global weight entropy outperformed all other global weighting functions.
as EBI signals are varying, the weighting function should have one or two parameters that could be used for adaptation to the waveform;
Different from the classical theory, CPT adopted a concave-shaped utility function (UF) for gains and convex for losses and an inverse S-shaped probability weighting function (PWF) to describe individual preferences for choosing between risky prospects.
This means that the time derivative of the step response shows how the preceding extraction rates influence the current fluid temperature; it is a weighting function for the preceding injection rates.
Position of weighting function in closed loop system will affect the shape of each related system function.
Such simple averaging is the most common method of time-aggregating higher-frequency variables; however, in principle, one could use any (normalized) weighting function.
This is due to the behavior of the weighting function defined in (22).
Formally, the model assumes an increasing utility function U[x] and a strictly increasing probability weighting function w : [0, 1] [right arrow] [0, 1] satisfying w(0) = 0 and w(l) = I such that the utility from a lottery that pays [x.
