摘要
A computer implemented method for calculating a scalar product a• x of a vector a and a vector x. the method comprises determining an estimator P, a vector α and a vector β, so that a• x= P+α•β, wherein the scalar product a•β has a dispersion that is smaller than the dispersion of the scalar product a• x.
