Codebook Dissimliarities — distance • pdc

Functions to calculate distances/dissimilarities between codebooks.

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.
