Creating Augmented Queries Using LangChain
Explore how to create augmented queries using LangChain to improve retrieval-augmented generation accuracy. Learn to refine query prompts by integrating retrieved context and questions, verify their structure, and enhance the quality of generated responses in RAG pipelines.
We'll cover the following...
Now that we’ve covered how LangChain and ChromaDB handle indexing and retrieval, let’s dive into the next crucial step: augmentation. Imagine you’re on a treasure hunt, and you’ve just found a map. The map is a bit faded, and you need to enhance it to see all the details clearly. In the world of RAG systems, our “map” is the retrieved information, and augmentation is the process of removing that blurriness.
Think of it this way: when we ask a question, our system embarks on a computational adventure, fetching bits of information from various sources, as we saw in the previous lesson. But before this information is handed over to the generator component—which is responsible for the final response—it needs to undergo preprocessing or, in our context, augmentation.
In this lesson, we’ll explore how augmentation works in LangChain with a practical example. We’ll learn how to refine queries ...
