多样化音频嵌入——重新引入特征优于CLAP!

Diverse Audio Embeddings -- Bringing Features Back Outperforms CLAP!

Stanford University(斯坦福大学)

Prateek Verma

AI总结:

本文提出将音高、音色等手工特征嵌入与端到端音频嵌入相结合,在数百类声音分类任务上显著超越纯端到端模型及CLAP性能。

摘要:

随着现代AI架构的出现,研究重心已转向端到端架构。这一转变使得神经架构在没有特定领域偏见/知识的情况下进行训练,并根据任务进行优化。在本文中,我们通过多样化的特征表示(在本例中为特定领域特征)来学习音频嵌入。针对数百种声音类别的音频分类任务,我们为音高、音色和神经表示等多种音频属性学习鲁棒的独立嵌入,同时通过端到端架构进行学习。我们观察到,手工设计的嵌入(例如基于音高和音色的嵌入)虽然单独使用时无法超越完全端到端的表示,但将它们与端到端嵌入结合使用,能够显著提升性能。这项工作将为在端到端模型中引入领域专业知识以学习鲁棒、多样化的表示铺平道路,从而超越仅训练端到端模型的性能。

英文摘要:

With the advent of modern AI architectures, a shift has happened towards end-to-end architectures. This pivot has led to neural architectures being trained without domain-specific biases/knowledge, optimized according to the task. We in this paper, learn audio embeddings via diverse feature representations, in this case, domain-specific. For the case of audio classification over hundreds of categories of sound, we learn robust separate embeddings for diverse audio properties such as pitch, timbre, and neural representation, along with also learning it via an end-to-end architecture. We observe handcrafted embeddings, e.g., pitch and timbre-based, although on their own, are not able to beat a fully end-to-end representation, yet adding these together with end-to-end embedding helps us, significantly improve performance. This work would pave the way to bring some domain expertise with end-to-end models to learn robust, diverse representations, surpassing the performance of just training end-to-end models.
