AI总结:

针对跨文本、音乐、动作三模态生成缺乏时间同步数据的问题,研究提出统一多模态模型UniMuMo,通过节奏对齐未配对数据、音乐码本编码动作等架构改进,微调单模态预训练模型实现多任务生成,在各基准上取得有竞争力的结果。

摘要:

我们提出了UniMuMo,这是一种统一多模态模型,能够以任意文本、音乐和动作数据作为输入条件,生成跨全部三种模态的输出。为解决时间同步数据匮乏的问题,我们基于节奏模式对齐未配对的音乐与动作数据,以利用现有的大规模纯音乐和纯动作数据集。通过将音乐、动作和文本转换为基于token的表示,我们的模型借助统一的编码器-解码器Transformer架构实现这些模态的桥接。为在单一框架内支持多种生成任务,我们引入了多项架构改进:提出用音乐码本对动作进行编码,将动作映射到与音乐相同的特征空间;引入音乐-动作并行生成方案,将所有音乐和动作生成任务统一到单个Transformer解码器架构中,仅需音乐-动作联合生成这一项训练任务。此外,该模型通过微调现有预训练单模态模型构建,大幅降低了计算需求。大量实验表明,UniMuMo在音乐、动作和文本模态的所有单向生成基准上均取得了具有竞争力的结果,量化结果可在项目页面查看。

英文摘要:

We introduce UniMuMo, a unified multimodal model capable of taking arbitrary text, music, and motion data as input conditions to generate outputs across all three modalities. To address the lack of time-synchronized data, we align unpaired music and motion data based on rhythmic patterns to leverage existing large-scale music-only and motion-only datasets. By converting music, motion, and text into token-based representation, our model bridges these modalities through a unified encoder-decoder transformer architecture. To support multiple generation tasks within a single framework, we introduce several architectural improvements. We propose encoding motion with a music codebook, mapping motion into the same feature space as music. We introduce a music-motion parallel generation scheme that unifies all music and motion generation tasks into a single transformer decoder architecture with a single training task of music-motion joint generation. Moreover, the model is designed by fine-tuning existing pre-trained single-modality models, significantly reducing computational demands. Extensive experiments demonstrate that UniMuMo achieves competitive results on all unidirectional generation benchmarks across music, motion, and text modalities.
