- OFAI-TR-2010-07 (
252kB PDF file)Hubs and Orphans - an Explorative Approach
- Martin Gasser, Arthur Flexer, Dominik Schnitzer
- In audio based music similarity, a well known effect is
the existence of hubs, i.e. songs which appear similar to
many other songs without showing any meaningful perceptual
similarity. We show that this effect depends on
the homogeneity of the samples under consideration. We
compare three small sound collections (consisting of polyphonic
music, environmental sounds, and samples of individual
musical instruments) with regard to their hubness.
We find that the collection consisting of cleanly recorded
musical instruments produces the smallest hubs, wheras
hubness increases with inhomogeneity of the audio signals.
We also investigate how well the three data sets can be
mapped into a 2D visualization space by a dimensionality
reduction algorithm based on Multidimensional Scaling.
