All Known Subinterfaces:

SMAggregateEuclidian

All Known Implementing Classes:

SMAggregateEuclidianImpl, SMAggregateMinkowskiImpl

public interface SMAggregateMinkowski
extends SMAggregateWeighted

The Minkowski aggregation is a generalization of this weighted average. The higher the value of the parameter p ≥ 1, the higher is the influence of the attribute with the highest local similarity. For p to infinity this aggregation function becomes the maximum aggregation.

Φ(s, …, s_i) = (∑ⁿ_i=1 (ω_i · s^p_i))^1/p
