摘要翻译：
声部分离是将音乐录音中的声乐部分和器乐部分分离出来的一种方法，是音乐信息检索中的一个基本问题。近年来对歌唱声音分离的研究表明，低阶表示和知情分离方法都能提高分离质量。然而，由于使用奇异值分解，低秩优化在计算上是低效的。因此，本文提出了一种新的线性时间算法，称为知情群稀疏表示，并利用基音注释作为辅助信息来分离人声和音乐。在iKala数据集上的实验结果证实了我们的方法的有效性，表明音乐伴奏遵循一个预先训练的器乐词典的群体稀疏结构。我们还展示了如何使用DSD100数据集轻松地扩展我们的工作以适应多个词典。

英文摘要：
Singing voice separation attempts to separate the vocal and instrumental parts of a music recording, which is a fundamental problem in music information retrieval. Recent work on singing voice separation has shown that the low-rank representation and informed separation approaches are both able to improve separation quality. However, low-rank optimizations are computationally inefficient due to the use of singular value decompositions. Therefore, in this paper, we propose a new linear-time algorithm called informed group-sparse representation, and use it to separate the vocals from music using pitch annotations as side information. Experimental results on the iKala dataset confirm the efficacy of our approach, suggesting that the music accompaniment follows a group-sparse structure given a pre-trained instrumental dictionary. We also show how our work can be easily extended to accommodate multiple dictionaries using the DSD100 dataset.
