Use of the Nonparametric Nearest Neighbor Approach to Estimate Soil Hydraulic Properties

  title={Use of the Nonparametric Nearest Neighbor Approach to Estimate Soil Hydraulic Properties},
  author={Attila Nemes and Walter J. Rawls and Yakov A. Pachepsky},
Nonparametric approaches are being used in various fields to address classification type problems, as well as to estimate continuous variables. One type of the nonparametric lazy learning algorithms, a k-nearest neighbor (k-NN) algorithm has been applied to estimate water retention at 233and 21500-kPa matric potentials. Performance of the algorithm has subsequently been tested against estimations made by a neural network (NNet) model, developed using the same data and input soil attributes.We… CONTINUE READING
