- Arthur Flexer, Dominik Schnitzer, Jan Schlueter
- We use results from the 2011 MIREX ``Audio Music Similarity and
Retrieval'' task for a meta analysis of the hub phenomenon. Hub songs
appear similar to an undesirably high number of other songs due to a
problem of measuring distances in high dimensional spaces. Comparing
17 algorithms we are able to confirm that different algorithms produce
very different degrees of hubness. We also show that hub songs exhibit
less perceptual similarity to the songs they are close to, according
to an audio similarity function, than non-hub songs. Application of
the recently introduced method of ``mutual proximity'' is able to
decisively improve this situation.
