摘要:

符号化音乐情感识别(SMER)是从符号化数据中预测音乐情感,如XML和MusicXML。以往的工作主要集中在通过(mask)语言模型预训练来学习更好的表征,而忽略了音乐的内在结构,这对音乐的情感表达至关重要。在本文中,我们提出了一个简单的多任务框架SMER,它结合了情感识别任务与其他情感相关的辅助任务来自音乐的内在结构。结果表明,我们的多任务框架可以适应不同的模型。此外,辅助任务的标签很容易获得,这意味着我们的多任务方法不需要人工标注的标签以外的情绪。在两个公开的数据集(EMOPIA和VGRESS)上进行的实验表明,该方法在SMER任务中具有较好的性能。具体而言,在EMOPIA数据集中,准确度增加了4.17个绝对点,达到67.58,在VGlombians数据集中,准确度增加了1.97个绝对点,达到55.85。消融研究也表明本文设计的多任务方法的有效性。

英文摘要:

Symbolic Music Emotion Recognition(SMER) is to predict music emotion from symbolic data, such as MIDI and MusicXML. Previous work mainly focused on learning better representation via (mask) language model pre-training but ignored the intrinsic structure of the music, which is extremely important to the emotional expression of music. In this paper, we present a simple multi-task framework for SMER, which incorporates the emotion recognition task with other emotion-related auxiliary tasks derived from the intrinsic structure of the music. The results show that our multi-task framework can be adapted to different models. Moreover, the labels of auxiliary tasks are easy to be obtained, which means our multi-task methods do not require manually annotated labels other than emotion. Conducting on two publicly available datasets (EMOPIA and VGMIDI), the experiments show that our methods perform better in SMER task. Specifically, accuracy has been increased by 4.17 absolute point to 67.58 in EMOPIA dataset, and 1.97 absolute point to 55.85 in VGMIDI dataset. Ablation studies also show the effectiveness of multi-task methods designed in this paper.
