RAG-Driven Generative AI

RAG Embedding Vector Stores with Deep Lake and OpenAI

There will come a point in the execution of your project where complexity is unavoidable when implementing RAG-driven generative AI. Embeddings transform bulky structured or unstructured texts into compact, high-dimensional vectors that capture their semantic essence, enabling faster and more efficient information retrieval. However, we will inevitably be faced with a storage issue as the creation and storage of document embeddings become necessary when managing increasingly large datasets. You could ask the question at this point, why not use keywords instead of embeddings? And the answer is simple: although embeddings require more storage space, they capture the deeper semantic meanings of texts, with more nuanced and context-aware retrieval compared to the rigid and often-matched keywords. This results in better, more pertinent retrievals. Hence, our option is to turn to vector stores in which embeddings are organized and rapidly...

Evaluating the output with cosine similarity

In this section, we will implement cosine similarity to measure the similarity between user input and the generative AI model’s output. We will also measure the augmented user input with the generative AI model’s output. Let’s first define a cosine similarity function:

from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.metrics.pairwise import cosine_similarity
def calculate_cosine_similarity(text1, text2):
    vectorizer = TfidfVectorizer()
    tfidf = vectorizer.fit_transform([text1, text2])
    similarity = cosine_similarity(tfidf[0:1], tfidf[1:2])
    return similarity[0][0]

Then, let’s calculate a score that measures the similarity between the user prompt and GPT-4’s response:

similarity_score = calculate_cosine_similarity(user_prompt, gpt4_response)
print(f"Cosine Similarity Score: {similarity_score:.3f}")

The score is low, although the output seemed...

Rothman has once again delivered something exceptional with RAG-Driven Generative AI. As expected from Rothman, this book shines in its ability to make complex topics accessible and practical, making it a standout in the growing literature on RAG systems. If you're looking for one of the best resources on RAG, packed with Python code and real-world applications, this book will not let you down.For readers keen to get hands-on, the book does not disappoint. Rothman provides a wealth of Python code throughout, with step-by-step examples that make it easy to follow along and implement RAG-driven solutions. Each chapter concludes with questions to test your understanding, reinforcing key concepts and ensuring that you grasp the material before moving on. For beginners and experienced practitioners alike, this interactive approach adds immense value to the learning experience.Chapter 4, Building a RAG Pipeline, is particularly valuable, offering clear instructions on how to build an end-to-end RAG system. The chapter walks readers through the process of designing a robust RAG pipeline. In addition, Rothman explores cutting-edge tools such as LlamaIndex, Deep Lake, and OpenAI to illustrate how to leverage them effectively for RAG-based projects. The comprehensive nature of this chapter makes it an essential guide for anyone looking to develop RAG systems from scratch or optimise existing ones.However, the most enlightening part of the book for this reader was Chapter 5: Boosting RAG Performance with Expert Human Feedback. This chapter delves into the creation of an adaptive RAG system that can evolve based on user feedback. Rothman guides readers through building a hybrid adaptive RAG program in Python on Google Colab. This hands-on project not only gives readers a solid grasp of adaptive RAG processes but also demonstrates how to adjust a system when predefined models fail to meet user expectations. Rothman goes further to show how human feedback, gathered through user rankings, can be integrated to fine-tune RAG systems, ensuring that the AI continues to meet users' needs. The chapter concludes with the implementation of an automated ranking system to enhance the generative model's performance, making it highly applicable to real-world business settings.In conclusion, RAG-Driven Generative AI is a must-read for anyone involved with LLMs. Rothman has delivered an insightful, practical, and highly recommended resource for anyone looking to explore RAG systems. Highly recommended.

I have been reading this new book on generative artificial intelligence complemented with RAG (Retrieval-Augmented Generation) and I find it quite useful and interesting.LLM models are advanced artificial intelligence systems designed to process and generate human language.They are trained with enormous amounts of text from several sources, to understand and respond coherently to a wide variety of questions and requests, but this also carries the disadvantage that they may not have the most relevant information for an organization, since it was not available when the model was trained, either due to time or confidentiality issues.Retrieval enhanced generation (RAG) is the process of optimizing the output so that it references an personalized knowledge base before generating a response.This allows the GAI to produce more useful and reliable responses to the organization's users.This book is one of the most complete and up-to-date references on how to use RAG techniques to improve the responses that GAI tools provide to organizational users.The book contains many examples on how use the different types of RAG, including the necessary code to incorporate it into your projects quickly and efficiently.Highly recommended for all practitioners, developers, and students of the topic of generative artificial intelligence.

RAG being in the forefront of Gen AI LLM models is a highly sought after skill or knowledge to have.This book covers the theory part of RAG, vectorization, Vector databases.Yet what I found most fascinating was the code snippets, applications that you can directly use in your GenAI application with a bit of modification.Just one advice be clear on Transformer and language models before learning RAG.For this I would recommend Denis's other book Transformers for NLP.
