Comparison Among AlexNet, GoogLeNet and ResNet-18 in Autiomatic Music Genre Classification

Abstract

This paper compared the performance among three famous convolutional neural networks in classifying music genres. Being carried out on a prominent dataset named Free Music Archive, the experiments show that ResNet-18 performs much better than AlexNet and GoogLeNet in classifying the music genres in a relatively small dataset. Meanwhile, the classification accuracy of each model for each music genre was also recorded. It indicates that different models could be expert in identifying distinct genres. Several genres, including blues, hip-hop and international, were not closely related to the change of models. In general, ResNet-18 reached the highest average classification accuracy at approximate 80%, while AlexNet did best in finding hip-hop music and GoogLeNet had relatively less difference in recognition rates for every genre. Those findings can serve as a reference in future music genre classification tasks and personalized music recommendation based on big data.
