核心概念
The author proposes a structure-informed positional encoding framework for music generation with Transformers to enhance coherence and long-term organization in generated music.
要約
The content discusses the development of a novel positional encoding framework called StructurePE for music generation using Transformers. Three variants are explored, each focusing on different aspects of positional information. The study compares these variants with baselines from the literature and demonstrates improved melodic and structural consistency in the generated music. The experiments cover tasks like next-timestep prediction and accompaniment generation, showcasing the effectiveness of the proposed methods. Additionally, insights into input representation, positional encoding techniques, and evaluation metrics are provided to support the findings.
統計
"We use a binary pianoroll representation for the input, using a resolution of 16 timesteps for one quarter note."
"A 2-layer Transformer decoder with 4 heads was used for training."
"SSMD, CS, GS, and NDD were among the evaluation metrics employed."
"APE performs poorly on length generalization at N1 but competes well at A2."
引用
"We propose three variants of StructurePE: S-APE, S-RPE, and NS-RPE."
"Our methods outperform baselines on SSMD in accompaniment generation."
"NoPE should be considered a serious contender in future work on music generation."
