AI总结:

本研究比较了CNN、VGG16和XGBoost在30秒Mel频谱图与3秒MFCCs特征下的音乐流派分类性能,发现MFCC XGBoost模型表现最佳,且数据分割能显著提升CNN性能。

摘要:

近年来,各种精心设计的算法赋予了音乐平台根据用户偏好提供内容的能力。音乐流派通过声学特征和文化考量等多个方面来定义。音乐流派分类与基于内容的过滤配合良好,该过滤根据音乐相似性向用户推荐内容。给定一个相当大的数据集,一个前提是使用机器学习或深度学习方法进行自动标注,从而有效地对音频文件进行分类。系统的有效性在很大程度上取决于特征和模型选择,因为不同的架构和特征可以相互促进并产生不同的结果。在本研究中,我们进行了一项对比研究,调查了三种模型的性能:一个提出的卷积神经网络(CNN)、带有全连接层(FC)的VGG16以及一个极限梯度提升(XGBoost)方法,使用了不同的特征:30秒Mel频谱图和3秒Mel频率倒谱系数(MFCCs)。结果表明,MFCC XGBoost模型的性能优于其他模型。此外,在数据预处理阶段应用数据分割可以显著增强CNN的性能。

英文摘要:

In recent years, various well-designed algorithms have empowered music platforms to provide content based on one's preferences. Music genres are defined through various aspects, including acoustic features and cultural considerations. Music genre classification works well with content-based filtering, which recommends content based on music similarity to users. Given a considerable dataset, one premise is automatic annotation using machine learning or deep learning methods that can effectively classify audio files. The effectiveness of systems largely depends on feature and model selection, as different architectures and features can facilitate each other and yield different results. In this study, we conduct a comparative study investigating the performances of three models: a proposed convolutional neural network (CNN), the VGG16 with fully connected layers (FC), and an eXtreme Gradient Boosting (XGBoost) approach on different features: 30-second Mel spectrogram and 3-second Mel-frequency cepstral coefficients (MFCCs). The results show that the MFCC XGBoost model outperformed the others. Furthermore, applying data segmentation in the data preprocessing phase can significantly enhance the performance of the CNNs.
