Overview of this book

RAG-Driven Generative AI provides a roadmap for building effective LLM, computer vision, and generative AI systems that balance performance and costs. This book offers a detailed exploration of RAG and how to design, manage, and control multimodal AI pipelines. By connecting outputs to traceable source documents, RAG improves output accuracy and contextual relevance, offering a dynamic approach to managing large volumes of information. This AI book shows you how to build a RAG framework, providing practical knowledge on vector stores, chunking, indexing, and ranking. You’ll discover techniques to optimize your project’s performance and better understand your data, including using adaptive RAG and human feedback to refine retrieval accuracy, balancing RAG with fine-tuning, implementing dynamic RAG to enhance real-time decision-making, and visualizing complex data with knowledge graphs. You’ll be exposed to a hands-on blend of frameworks like LlamaIndex and Deep Lake, vector databases such as Pinecone and Chroma, and models from Hugging Face and OpenAI. By the end of this book, you will have acquired the skills to implement intelligent solutions, keeping you competitive in fields from production to customer service across any project.

Keyword index query engine

KeywordTableIndex is a type of index in LlamaIndex, designed to extract keywords from your documents and organize them in a table-like structure. This structure makes it easier to query and retrieve relevant information based on specific keywords or topics. Once again, don’t think about this function as a simple list of extracted keywords. The extracted keywords are organized into a table-like format where each keyword is associated with an ID that points to the related nodes.

The program creates the keyword index in two lines of code:

from llama_index.core import KeywordTableIndex
keyword_index = KeywordTableIndex.from_documents(documents)

Let’s extract the data and create a pandas DataFrame to see how the index is structured:

# Extract data for DataFrame
data = []
for keyword, doc_ids in keyword_index.index_struct.table.items():
    for doc_id in doc_ids:
        data.append({"Keyword": keyword, "Document ID...
