AI总结:

针对现有语音-图像检索方法难以捕捉模态细粒度细节的问题,提出仅在训练阶段使用的跨模态去噪任务增强跨模态对齐,在两个基准数据集上取得了优于现有方法的检索性能,且不增加推理耗时。

摘要:

语音-图像检索的成功依赖于在语音和图像之间建立有效的对齐关系。现有方法通常通过各模态全局特征的简单余弦相似度来建模跨模态交互,这类方法不足以捕捉模态内部的细粒度细节。为解决这一问题,我们提出了一个有效框架以及一项名为cross-modal denoising(CMD,跨模态去噪)的新型学习任务,用以增强跨模态交互,实现更细粒度的跨模态对齐。具体而言,CMD是一项去噪任务,旨在通过与另一模态的特征交互,从单模态的含噪特征中重建语义特征。值得注意的是,CMD仅在模型训练阶段运行,推理阶段可将其移除,不会增加额外推理时间。实验结果表明,在语音-图像检索任务中,我们的框架在Flickr8k数据集上的平均R@1优于当前最优方法2.0%,在SpokenCOCO数据集上的平均R@1优于当前最优方法1.7%。这些实验结果验证了我们框架的效率与有效性。

英文摘要:

The success of speech-image retrieval relies on establishing an effective alignment between speech and image. Existing methods often model cross-modal interaction through simple cosine similarity of the global feature of each modality, which fall short in capturing fine-grained details within modalities. To address this issue, we introduce an effective framework and a novel learning task named cross-modal denoising (CMD) to enhance cross-modal interaction to achieve finer-level cross-modal alignment. Specifically, CMD is a denoising task designed to reconstruct semantic features from noisy features within one modality by interacting features from another modality. Notably, CMD operates exclusively during model training and can be removed during inference without adding extra inference time. The experimental results demonstrate that our framework outperforms the state-of-the-art method by 2.0% in mean R@1 on the Flickr8k dataset and by 1.7% in mean R@1 on the SpokenCOCO dataset for the speech-image retrieval tasks, respectively. These experimental results validate the efficiency and effectiveness of our framework.
