The collection of theater music data and genre recognition under the internet of things and deep belief network

In order to improve the efficiency and accuracy of collecting theater music data and recognizing genres, and solve the problem that a single feature in traditional algorithms cannot efficiently classify music genres, the technology of collecting data based on the Internet of Things (IoT) and Deep Belief Network (DBN) is firstly proposed for application of collecting music data and recognizing genres. The study firstly introduces the scheme of collecting music data based on the Internet of Things (IoT) and the theoretical basis of the recognition and classification of music genres by DBN. Second, the study focuses on the construction and improvement of the music genre recognition algorithm under DBN. In other words, the algorithm is optimized by adding Dropout and momentum to the network, and the optimal network model after training is implemented. And finally, the effectiveness of the algorithm is confirmed by experiment and research. The experimental results show that the efficiency of the optimized algorithm of identifying the music genres in the music library reaches 75.8%, which is far better than the traditional classic algorithms in the past. It is concluded that the technology of music data collection and genre recognition based on IoT and DBN has strong advantages, which will greatly contribute to reducing the workload of manual collection and identification of classification features, and improve efficiency. Meanwhile, the optimized algorithm model can also be extended to other fields.
