Abstract

The application of traditional shallow model to instrument classification task has the problem of poor nonlinear fitting ability, so that the accuracy of classification was not guaranteed effectively. It is necessary to introduce deep learning method to improve the nonlinear modeling ability of complex tasks. This paper used deep Boltzmann machine as feature extractor to abstract more expressive deep learning features. It respectively used SVM and softmax classifier as top layer of deep neural network to form DBM+SVM and DBM+softmax combined model. Besides, this paper introduced the mean field theory and momentum factor to optimize the network training process, and compared the above two sets of models and single SVM classifier on 5 kinds of musical instruments audio data. The classification accuracy of the two types of deep learning combination models reached 89.29% and 87.5% respectively, compared with the accuracy of the traditional shallow classification method SVM of 73.21%. The experimental results show that the application of deep Boltzmann machine in the field of musical instrument classification is very promising.
