Struct Hellinger
Herlinger distance.
Namespace: ISynergy.Framework.Mathematics.Distances
Assembly: ISynergy.Framework.Mathematics.dll
Syntax
public struct Hellinger : IMetric<double[]>, IDistance<double[]>, IDistance<double[], double[]>Remarks
In probability and statistics, the Hellinger distance (also called Bhattacharyya distance as this was originally introduced by Anil Kumar Bhattacharya) is used to quantify the similarity between two probability distributions. It is a type of f-divergence. The Hellinger distance is defined in terms of the Hellinger integral, which was introduced by Ernst Hellinger in 1909.
