- Arthur Flexer, Elias Pampalk, Gerhard Widmer
- Hidden Markov Models (HMM) are compared to Gaussian Mixture Models
(GMM) for describing spectral similarity of songs. Contrary to
previous work we make a direct comparison based on the
log-likelihood of songs given an HMM or GMM. Whereas the direct
comparison of log-likelihoods clearly favors HMMs, this advantage in
terms of modeling power does not allow for any gain in genre
classification accuracy.
