SMAggregateKMinimum (ProCAKE Framework 3.0.1-SNAPSHOT API)

All Superinterfaces:

SimilarityMeasure, SMAggregate, SMAggregateWeighted

All Known Implementing Classes:

SMAggregateKMinimumImpl
```
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, …, s_i) = maxⁿ_{i_k} (ω_i · s_{i_k}) with (ω_i · s_{i_k}) ≤ (ω_i · s_{i_k})
