Advanced RAG-Related Techniques for Improving Results
In this final chapter, we explore several advanced techniques to improve retrieval-augmented generation (RAG) applications. These techniques go beyond the fundamental RAG approaches to tackle more complex challenges and achieve even better results. Our starting point will be techniques we have already used in previous chapters. We will build off those techniques, learning where they fall short so that we can introduce new techniques that can make up the difference and take your RAG efforts even further.
Throughout this chapter, you will gain hands-on experience implementing these advanced techniques through a series of code labs. Our topics will include the following:
- Naïve RAG and its limitations
- Hybrid RAG/multi-vector RAG for improved retrieval
- Re-ranking in hybrid RAG
- Code lab 14.1 – Query expansion
- Code lab 14.2 – Query decomposition
- Code lab 14.3 – Multi-modal RAG (MM...
