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.

Appendix

Querying the collection

The code in this section executes a query against the Chroma vector store using its integrated semantic search functionality. It queries the vector representations of all the vectors in the Chroma collection questions in the initial dataset:

dataset["question"][:nbq].

The query requests one most relevant or similar document for each question with n_results=1, which you can modify if you wish.

Each question text is converted into a vector. Then, Chroma runs a vector similarity search by comparing the embedded vectors against our database of document vectors to find the closest match based on vector similarity:

import time
start_time = time.time()  # Start timing before the request
# number of retrievals to write
results = collection.query(
    query_texts=df["question"][:nb],
    n_results=1)
response_time = time.time() - start_time  # Measure response time
print(f"Response Time: {response_time:.2f} seconds")  ...
