double apply(CompareFunction[] compareFunctions, double[] cluster, double[] data, double[] fieldWeights, double[] missingValueWeights, double[] similarityScales, double pParameter)
AggregationFunction
. Computes the distance/similarity
of two vectors.
Compare function, field weights, missing value weights and similarity
scales at index i must correspond to cluster and data vector values at
the same index.compareFunctions
- the CompareFunction
s to measure distance/similarity
between the vectorscluster
- the cluster seedsdata
- the data vectorfieldWeights
- field weights for each field/its valuesmissingValueWeights
- missing value weights for each field/its valuessimilarityScales
- similarity scales for each field/its valuespParameter
- the p-parameter, only used by the Minkowski functionString name()
boolean is(ComparisonMeasure.Kind kind)
