Content-Based Information Fusion for Semi-Supervised Music Genre Classification

In this paper, we propose an information fusion framework for the semi-supervised distance-based music genre classification problem. We make use of the regularized least-square framework as the basic classifier, which only involves the similarity scores among different music tracks. We present a similarity score that multiplies different scores based on different distance measures. Particularly the distance measures are not restricted to the Euclidean distance. By adding a weight to each single distance based score, we propose an expectation-maximization (EM) algorithm to adaptively learn the fusion scores. Experiments on real music data set show that our approach can give promising results.
