Deep Image Features in Music Information Retrieval

Applications of Convolutional Neural Networks ( CNNs ) to various problems have been the subject of a number of recent studiesranging from image classification and object detection to scene parsing, segmentation 3D volumetric images and action recognition in videos. In this study, the CNNs were applied to a Music Information Retrieval (MIR), in particular to musical genre recognition. The model was trained on ILSVRC-2012 (more than 1 million natural images) to perform image classification and was reused to perform genre classification using spectrograms images. Harmonic and percussion separation was applied, because it is characteristic formusical genre. At final stage, the evaluation of various strategies of merging Support Vector Machines (SVMs) was performed on well known in MIR community - GTZAN dataset. Even though, the model was trained on natural images, the results achieved in this studywere close to the state-of-the-art.
