Об одном методе оценки многомерной плотности на основеближайших соседей
A method of multivariate density estimation based on the reweighted nearest neighbours, mimicking the natural neighbours techniques, is presented. Estimation of multivariate density is important for machine learning, astronomy, biology, physics and econometrics. A 2-additive fuzzy measure is constructed based on proxies for pairwise interaction indices. The neighbours of a point lying in nearly the same direction are treated as redundant, and the contribution of the farthest neighbour is
