Hybrid DDM algorithm based on weight function;

The weight function SL,SC of CIEDE2000 color difference formula was revised for calculating medium color difference to accord with visual perception.

In the optimization model,according to steering request,a weight function was founded.

In this paper,through analysing the construction of some classic weighting functions,we will propose a term weighting modification approach based on text information space so that efficiency of text categorization and filtering is higher.

Based on the finite set of the lineal indepentent inverse filter of input signals,weighting function of Viner filter is acquired and an effective structure estimating of a digit filter for polynomial inverse function is showed.

We set up the subjective probabilities of the returns distributions based on the weighting function of the prospect theory.

In this paper,by using the theory of function structure,the author give the theory on nonstandard interpolation basic function,and generalize int erpolation basic function from standard form to nonstandard form.

The structural function is the result of structural method and is widelyused in mathematical field.
