Detailed Description

Neighborhood definition by Bench.

The Neighborhood is usually meant to select a sub-population from the input Data Base, containing the active samples close to the target.

The selected samples belong to the same 'bench' as the target: the distance (according to the last space coordinate, e.g. the elevation in the 3-D case) between a selected sample and the target is smaller than the bench width.

The neighborhood also offers the possibility to suppress any sample which would be too close to (or coincide with) the target: this is the cross-validation option.
