An evaluation of deep neural network models for music classification using spectrograms

Deep Neural Network (DNN) models have lately received considerable attention for that the network structure can extract deep features to improve classification accuracy and achieve excellent results in the field of image. However, due to the different content forms of music and images, transferring deep learning to music classification is still a problem. To address this issue, in the paper, we transfer the state-of-the-art DNN models to music classification and evaluate the performance of the models using spectrograms. Firstly, we convert the music audio files into spectrograms by modal transformation, and then classify music through deep learning. In order to alleviate the problem of overfitting during training, we propose a balanced trusted loss function and build the balanced trusted model ResNet50_trust. Finally, we compare the performance of different DNN models in music classification. Furthermore, this work adds music sentiment analysis based on the newly constructed music emotion dataset. Extensive experimental evaluations on three music datasets show that our proposed model Resnet50_trust consistently outperforms other DNN models.
