java.lang.Objectweka.core.NormalizableDistance
weka.core.ManhattanDistance
public class ManhattanDistance
Implements the Manhattan distance (or Taxicab geometry). The distance between two points is the sum of the (absolute) differences of their coordinates.
For more information, see:
Wikipedia. Taxicab geometry. URL http://en.wikipedia.org/wiki/Taxicab_geometry.
@misc{missing_id, author = {Wikipedia}, title = {Taxicab geometry}, URL = {http://en.wikipedia.org/wiki/Taxicab_geometry} }Valid options are:
-D Turns off the normalization of attribute values in distance calculation.
-R <col1,col2-col4,...> Specifies list of columns to used in the calculation of the distance. 'first' and 'last' are valid indices. (default: first-last)
-V Invert matching sense of column indices.
