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.

Barnes [34] and Maddox (1980) indicated that, prior to performing the Barnes filter, the weighting function coefficients C and G in (2) and (4) should be chosen so that pattern scales resolvable by the data distribution will be revealed to known response amplitude.
