DistMode

Declaration:

TMemBasedLearner.DistMode: TMBLDistMode;

The property DistMode controls the type of distance measure used for the calculations of object distances. Three modes are currently supported: mblDistEuclid The common Euclidean distance is the square root of the sum of all square differences of the variables. mblDistManhattan The Manhattan distance is the sum of the absolute values of all differences of the variables. mblDistMahalanobis The Mahalanobis distance takes of care of correlation effect and can be considered as the Euclidean distance in a decorrelated variable space. Please note that the Mahalanobis distance take considerable time to calculate.
