public interface SMAggregateKMinimum extends SMAggregateWeighted
The k-minimum aggregation is a generalization of the standard minimum aggregation. The k lowest local similarity value determines the global similarity. Hence, if k out of n attributes indicate a low utility, the overall utility for the whole case is low.Φ(s1, , si) = maxnik (ωi · sik) with (ωi · sik) ≤ (ωi · sik)
