SMAggregateKMaximum (ProCAKE Framework 3.0.1-SNAPSHOT API)

All Superinterfaces:

SimilarityMeasure, SMAggregate, SMAggregateWeighted

All Known Implementing Classes:

SMAggregateKMaximumImpl
```
public interface SMAggregateKMaximum
extends SMAggregateWeighted
```
The k-maximum aggregation is a generalization of the standard maximum aggregation. The k highest local similarity value determines the global similarity. Hence, if k out of n attributes indicate a high utility, the overall utility for the whole case is high.

Φ(s, …, s_i) = maxⁿ_{i_k} (ω_i · s_{i_k}) with (ω_i · s_{i_k}) ≥ (ω_i · s_{i_k})
