selfSimilarity

groupGroupingSimilarity

public double groupGroupingSimilarity(IObjectGroup group,
                                      IObjectGrouping grouping)

Uses getGroupRepresentation() in the ISimilarity. Treats it as if it is a centroid, to calcualate the average weight of all IObject:s to all IObject:s in the IObjectGroup. The similarity of all IObject:s to them selves are subtracted, so it becomes the the average similarity BETWEEN all IObject:s.

weightedAvgSelfSimilarity

public double weightedAvgSelfSimilarity(java.util.Vector<IObjectGroup> groups)

Uses getGroupRepresentation() in the ISimilarity. Treats it as if it is a centroid, to calcualate the average weight of all IObject:s of the IObjectGroup to all IObject:s in the IObjectGrouping. The similarity of all IObject:s to them selves are subtracted, so it becomes the the average similarity BETWEEN all IObject:s in the group to the all IObject:s in the grouping.
