> The implementation of Adamic-Adar Similarity [0] is very close to Jaccard Similarity. Whereas Jaccard Similarity counts common neighbors, Adamic-Adar Similarity sums the inverse logarithm of the degree of common neighbors.
> Consideration will be given to the computation of the inverse logarithm, in particular whether to pre-compute a small array of values.
