java.lang.Objectat.tuwien.ifs.somtoolbox.input.SOMLibDataWinnerMapping
public class SOMLibDataWinnerMapping
Reads and encapsules the input data - winner information. This means units that are the best-matching ones for the
single input data, and the distances to those units (the distances are used e.g. by the
SmoothedDataHistograms
in their weighted & normalised form.
