Interface illustration: details of moves
- Each move - refine, reduce, reassign - is an entire collection of possible moves, each with many possible choices.
- The next few slides illustrate the prototype implementation where:

- Once selected, each button pops up its own control panel where various different kinds of moves and parameter choices can be made. E.g. the analyst might choose to reduce by any of:
- Join groups with closest centres using Euclidean distance
- Join groups whose farthest points are closest (i.e. “complete linkage”)
- Choose group with greatest spread and disperse its points among the remaining groups. …
