How might you define the proximity between two sets of data objects? (Make no assumption about the data objects, except that a proximity measure is defined between any pair of objects.)
Proximity is typically defined between a pair of objects.
One approach is to compute the average pairwise proximity of objects
in one group of objects with those objects in the other group. Other
approaches are to take the minimum or maximum proximity.
Note that the cohesion of a cluster is related to the notion of the proximity
of a group of objects among themselves and that the separation of clusters
is related to concept of the proximity of two groups of objects.
