In the second article of the Building Multimodal RAG Application series, we explore the process of building a multimodal retrieval-augmented generation (RAG) application using multimodal embeddings.
We start by providing an overview of multimodal embeddings, explaining how they bridge different data types, such as text and images, by embedding them into a shared vector space.
Next, we introduce the Bridge Tower model, a state-of-the-art solution for computing these embeddings. The guide then walks through the process of setting up your work environment and computing multimodal embeddings for both text and images.
We will also cover techniques for measuring the similarity between these embedding vectors, which is crucial for cross-modal retrieval tasks. Finally, we demonstrate how to visualize high-dimensional embeddings using UMAP, enabling a deeper understanding of the structure and relationships within the data.
This comprehensive guide will equip you with the tools and knowledge to build a multimodal RAG system, enhancing your ability to work with text-image interactions.
