Parallel Algorithms for Combined Regularized Support Vector Machines: Application in Music Genre Classification
Authors: Rongmei Liang, Zizheng Liu, Xiaofei Wu, Jingwen Tu
In the era of rapid development of artificial intelligence, its applications span across diverse fields, relying heavily on effective data processing and model optimization. Combined Regularized Support Vector Machines (CR-SVMs) can effectively handle the structural information among data features, but there is a lack of efficient algorithms in distributed-stored big data. To address this issue, we propose a unified optimization framework based on consensus structure. This framework is not only applicable to various loss functions and combined regularization terms but can also be effectively extended to non-convex regularization terms, showing strong scalability. Based on this framework, we develop a distributed parallel alternating direction method of multipliers (ADMM) algorithm to efficiently compute CR-SVMs when data is stored in a distributed manner. To ensure the convergence of the algorithm, we also introduce the Gaussian back-substitution method. Meanwhile, for the integrity of the paper, we introduce a new model, the sparse group lasso support vector machine (SGL-SVM), and apply it to music information retrieval. Theoretical analysis confirms that the computational complexity of the proposed algorithm is not affected by different regularization terms and loss functions, highlighting the universality of the parallel algorithm. Experiments on synthetic and free music archiv datasets demonstrate the reliability, stability, and efficiency of the algorithm.

FMA Dataset: Identifying Key Features for Music Genre
Experiments on the publicly available Free Music Archiv (FMA) dataset, grouping 1036 features into 7 categories, demonstrated SGL-SVM's ability to effectively identify the most discriminative audio feature groups for music genre classification. This provides crucial insights for efficient model training and data storage.
- The MFCC feature group (Mel-frequency cepstral coefficients) was found to be the most crucial, mimicking human auditory perception and effectively capturing timbre and sound quality features.
- The spectral feature group ranked second, describing spectral shape and energy distribution. This includes features like spectral contrast and spectral flux.
- The chroma feature group played a relatively important role, capturing harmony and tonality information.
- Other four feature groups had minimal effect on classification accuracy, suggesting potential data storage savings by focusing on the top three for large-volume music data with limited memory.
