本文提出一种无需标注的测试时域适应方法,通过增强视图一致性学习域向量,在12个下游任务上平均零样本性能提升3.2%,且保持泛化能力。

摘要:

音频语言模型(ALM)旨在通过提供测试时的零样本能力来充当通用音频模型。ALM的零样本性能通过为每个域使用合适的文本提示而得到提升。文本提示通常通过临时过程手工制作,导致ALM的泛化能力和分布外性能下降。现有的提升域性能的方法,如少样本学习或微调,需要访问标注数据和训练迭代。因此,我们提出了一种针对ALM的测试时域适应方法,该方法无需访问标注。我们的方法通过强制测试音频的增强视图之间的一致性来学习域向量。我们在跨域的12个下游任务上广泛评估了我们的方法。仅凭一个示例,我们的域适应方法平均零样本性能提升了3.2%(最大8.4%)。适应后,模型仍保留ALM的泛化特性。

英文摘要:

Audio-Language Models (ALM) aim to be general-purpose audio models by providing zero-shot capabilities at test time. The zero-shot performance of ALM improves by using suitable text prompts for each domain. The text prompts are usually hand-crafted through an ad-hoc process and lead to a drop in ALM generalization and out-of-distribution performance. Existing approaches to improve domain performance, like few-shot learning or fine-tuning, require access to annotated data and iterations of training. Therefore, we propose a test-time domain adaptation method for ALMs that does not require access to annotations. Our method learns a domain vector by enforcing consistency across augmented views of the testing audio. We extensively evaluate our approach on 12 downstream tasks across domains. With just one example, our domain adaptation method leads to 3.2% (max 8.4%) average zero-shot performance improvement. After adaptation, the model still retains the generalization property of ALMs.
