abstract saturated hydraulic conductivity (ks) is needed for many studies related to water and solute transport, but often cannot be measured because of practical and/or cost-related reasons. nonparametric approaches are being used in various fields to estimate continuous variables. one type of the nonparametric lazy learning algorithms, a k-nearest neighbor (k-nn) algorithm, was introduced and...

kernel density estimators are the basic tools for density estimation in non-parametric statistics.  the k-nearest neighbor kernel estimators represent a special form of kernel density estimators, in  which  the  bandwidth  is varied depending on the location of the sample points. in this paper‎, we  initially introduce the k-nearest neighbor kernel density estimator in the random left-truncatio...

Consider a dataset of n(d) points generated independently from R according to a common p.d.f. fd with support(fd) = [0, 1] d and sup{fd([0, 1] )} growing sub-exponentially in d. We prove that: (i) if n(d) grows sub-exponentially in d, then, for any query point ~q ∈ [0, 1] and any ǫ > 0, the ratio of the distance between any two dataset points and ~q is less that 1 + ǫ with probability → 1 as d ...
