Thong Nguyen, Mariya Hendriksen, Andrew Yates

AI总结:

本研究探索多模态学习稀疏检索(MLSR)在图像推荐任务中的应用,发现利用图像标题丰富图像内容能显著提升模型性能,为多模态环境下的LSR模型训练提供了有效方案。

摘要:

学习稀疏检索(LSR)是一组旨在将查询和文档编码为稀疏词汇向量的神经方法。这些向量可以使用倒排索引进行高效索引和检索。尽管LSR在文本检索中展现出潜力,但其在多模态检索中的潜力在很大程度上仍未被探索。受此启发,在本研究中,我们探索了LSR在多模态领域的应用,即我们专注于多模态学习稀疏检索(MLSR)。我们使用几种MLSR模型配置进行了实验,并评估了在图像推荐任务上的性能。我们发现仅基于图像内容来解决该任务具有挑战性。用图像的标题丰富图像内容可显著提升模型性能,这表明图像标题对于提供图像的细粒度概念和上下文信息具有重要意义。我们的方法为在多模态环境中训练LSR检索模型提供了一种实用且有效的解决方案。

英文摘要:

Learned Sparse Retrieval (LSR) is a group of neural methods designed to encode queries and documents into sparse lexical vectors. These vectors can be efficiently indexed and retrieved using an inverted index. While LSR has shown promise in text retrieval, its potential in multi-modal retrieval remains largely unexplored. Motivated by this, in this work, we explore the application of LSR in the multi-modal domain, i.e., we focus on Multi-Modal Learned Sparse Retrieval (MLSR). We conduct experiments using several MLSR model configurations and evaluate the performance on the image suggestion task. We find that solving the task solely based on the image content is challenging. Enriching the image content with its caption improves the model performance significantly, implying the importance of image captions to provide fine-grained concepts and context information of images. Our approach presents a practical and effective solution for training LSR retrieval models in multi-modal settings.
