Computes the set of Pareto-optimal cluster sizes in obj according to the values of the cluster validation indices. A ranking of optimal cluster sizes and a table illustrating the ranking of solutions are returned.
analyzePareto(obj)
Arguments
obj: A matrix returned by mocca in its objectiveVals component. This matrix contains the values of several cluster validation indices for different cluster algorithms and different cluster sizes.
Returns
A list with the following components - rank: A vector containing the ranking of the Pareto-optimal cluster sizes.
table: A table specifying the ranking of Pareto-optimal cluster sizes. Each row is associated with a particular Pareto-optimal cluster size. Its entries specify in how many objective functions it dominates clusterings of other cluster sizes. The Pareto-optimal cluster sizes are ranked by the minimum number of objectives in which they dominate other cluster sizes.
