music. We have evaluated several alternatives using Gaussian mixture
models, fuzzy c-means, and k-means pursuing the assumption
that a piece of music contains significantly different rhythm patterns.
However, the median, despite being by far the simplest technique,
yielded comparable results to the more complex methods. Other
simple alternatives such as the the mean proved to be too vulnerable
with respect to outliers.
