In this context, we have seen the growing of musical recommendation systems, which can improve the benefits for several applications, such as social networks and collective musical libraries. In this work, we have introduced a recent machine learning technique named Optimum-Path Forest (OPF) for musical genre classification, which has been demonstrated to be similar to the state-of-the-art pattern recognition techniques, but much faster for some applications. Experiments in two public datasets were conducted against Support Vector Machines and a Bayesian classifier to show the validity of our work. In addition, we have executed an experiment using very recent hybrid feature selection techniques based on OPF to speed up feature extraction process. © 2011 International Society for Music Information Retrieval.699-704engBayesian classifierHybrid feature selectionsMachine learning techniquesMusical genre classificationOptimum-path forestsPattern recognition techniquesSocial NetworksSpeed upExperimentsFeature extractionForestryInformation retrievalLearning systemsClassification (of information)ClassificationExperimentationInformation RetrievalTrabalho apresentado em eventoAcesso aberto2-s2.0-848735755540140365057016044
