distance: Codebook Dissimliarities

Description

Functions to calculate distances/dissimilarities between codebooks.

Usage

hellingerDistance(x,y)
squaredHellingerDistance(x,y)
symmetricAlphaDivergence(x,y)

Arguments

x

a codebook

y

a codebook

Value

Returns a numeric dissimilarity between two codebooks.

Details

Note: The symmetric alpha-divergence is proportional to the Squared Hellinger distance, and is the default divergence between codebooks.
