Advanced RAG Pipeline – RAG Paradigm

Prasanth Sai
July 1, 2024

Introduction

Retrieval-Augmented Generation (RAG) is a cutting-edge methodology that combines retrieval methods to address the static limitations of large language models (LLMs). This integration allows models to dynamically incorporate up-to-date external information, enhancing their accuracy and reliability by grounding responses in real-world data. This blog talks about a more advanced RAG pipeline called The RAG paradigm, which is structured into four main phases: pre-retrieval, retrieval, post-retrieval, and generation, each contributing uniquely to the overall effectiveness of the pipeline.

Advanced RAG pipeline

Pre-Retrieval

Indexing: The pre-retrieval phase lays the groundwork for efficient information retrieval. It begins with indexing, where data is prepared for quick and accurate access. This involves text normalization (tokenization, stemming, stop word removal) and the organization of text into sentences or paragraphs. Advanced indexing techniques use pre-trained language models (LMs) to generate semantic vector representations of texts, stored for rapid retrieval.

Query Manipulation: This involves refining user queries to better align with the indexed data. Techniques include query reformulation (rewriting queries for clarity), query expansion (adding synonyms or related terms), and query normalization (standardizing spelling and terminology).

Data Modification: This step enhances retrieval efficiency by preprocessing data to remove irrelevant or redundant information and enrich it with metadata, improving the relevance and diversity of retrieved content.

Retrieval

Search & Ranking: The retrieval stage combines search and ranking to select and prioritize documents from the dataset. Traditional retrieval methods like BM25 are enhanced with pre-trained LMs like BERT, which capture the semantic essence of queries more effectively. These models measure vector distances between documents and queries, refining document ranking through semantic similarities, thus improving search accuracy.

Post-Retrieval

Re-Ranking: Post-retrieval involves refining initially retrieved documents to improve generation quality. Re-ranking reassesses and reorganizes documents based on additional metrics and external knowledge sources, highlighting the most relevant documents.

Filtering: This step removes documents that do not meet quality or relevance standards, often using relevance evaluations like sending entities to filter documents or create summaries of the documents and use only relevant to the user query, etc to ensure only the most pertinent documents are used for generation.

Generation

Enhancing: The generation phase merges retrieved information with the user’s query to create a coherent and relevant response. This involves elaboration, rephrasing, and restructuring to improve the clarity, coherence, and stylistic appeal of the output.

Customization: Optional but valuable, customization adapts the content to meet specific user preferences or contextual needs. This includes summarizing, condensing information, and aligning the output with the target audience or presentation format.

Advanced RAG Techniques

Multi-Hop Retrieval: Unlike single-hop retrieval, which retrieves information in one step, multi-hop retrieval iterates between retrieval and generation. This iterative process refines the accuracy and relevance of retrieved information, significantly improving the quality of the final output.

Modular RAG Platforms: Platforms like LangChain and LlamaIndex modularize the RAG approach, enhancing adaptability and expanding its range of applications. These platforms maintain the fundamental RAG workflow while employing diverse methodologies to tackle different aspects of RAG, such as multiple search iterations and iterative generation.

Innovative Retrieval Methods: Recent advancements include Differentiable Search Indices, which integrate retrieval within a Transformer model, and Generative Models for Search, which generate document titles and evidence sentences for fact-verification tasks. These methods offer superior performance and efficiency.

Enhanced Indexing: Techniques like FAISS (Facebook AI Similarity Search) and hierarchical navigable small-world (HNSW) graphs improve retrieval speed and accuracy. Innovations like MEMWALKER create a memory tree from input text, efficiently managing large volumes of information.

Sophisticated Query Manipulation: Methods such as Step-Back and PROMPTAGATOR abstract high-level concepts and utilize LLMs for prompt-based query generation. These strategies better align queries with retrieval systems, enhancing retrieval relevance and insight.

Evaluation and Future Directions

Evaluation Frameworks: Evaluating RAG systems involves assessing the quality of the generated text, the relevance of retrieved documents, and resilience to misinformation. Metrics like Exact Match (EM) and F1 scores are standard, but new frameworks also consider noise robustness, negative prompting, and counterfactual robustness.

Multimodal RAG: Combining textual and visual information for language generation is a growing area. Models like MuRAG and Re-Imagen enhance visual question answering and text-to-image generation, showcasing the potential of multimodal RAG.

Improving Retrieval Quality: Future research aims to enhance retrieval methods, focusing on integrating retrieval with language generation models to handle vast amounts of data effectively and reliably.

Conclusion

The RAG paradigm offers a robust framework for integrating retrieval methods with LLMs, significantly improving their accuracy and reliability. By structuring the workflow into pre-retrieval, retrieval, post-retrieval, and generation phases, RAG provides a comprehensive approach to leveraging real-world data. As advancements continue, particularly in multi-hop retrieval and multimodal RAG, the potential applications and adaptability of RAG are set to expand, driving further innovations in the field of natural language processing.

Step 2: Function to Extract All Images from the PDF

Define a function to extract images from the PDF:

def extract_images(pdf_path, output_folder):
    pdf_document = fitz.open(pdf_path)
    for page_num in range(len(pdf_document)):
        page = pdf_document[page_num]
        image_list = page.get_images(full=True)
        for image_index, img in enumerate(image_list):
            xref = img[0]
            base_image = pdf_document.extract_image(xref)
            image_bytes = base_image["image"]
            image_ext = base_image["ext"]
            image_filename = f"image_{page_num + 1}_{image_index + 1}.{image_ext}"
            with open(os.path.join(output_folder, image_filename), "wb") as image_file:
                image_file.write(image_bytes)
    pdf_document.close()

Step 3: Function to Replace Images in the PDF with Image Path Placeholders

Create a function to replace images in the PDF with placeholders:

def replace_images_with_placeholders(pdf_path, output_pdf_path, image_positions):
    pdf_document = fitz.open(pdf_path)
    for page_number, images in image_positions.items():
        page = pdf_document.load_page(page_number)
        images.sort(key=lambda x: (x[0].y0, x[0].x0))  # Sort images by their position on the page
        for rect, image_filename in images:
            placeholder_text = f"[{image_filename}]"
            page.insert_textbox(rect, placeholder_text, fontsize=12, color=(0, 0, 0))
    pdf_document.save(output_pdf_path)

Step 4: Convert the Modified PDF to Markdown with the Right Image Path Format

Use pymudf4llm to convert the modified PDF to Markdown:

def convert_pdf_to_markdown(pdf_path, image_folder):
    output_markdown_path = "output.md"
    pymudf4llm.convert(pdf_path, output_markdown_path, image_folder=image_folder)
    return output_markdown_path

Step 5: Replace the image paths in the markdown with right markdown image format

Function to replace image placeholders with the right markdown format:

def convert_into_markdownimages(markdown_path, output_folder):
    with open(markdown_path, "r") as md_file:
        lines = md_file.readlines()

    new_lines = []
    image_pattern = re.compile(r'\[([^\]]+\.png)\]')

    for line in lines:
        matches = image_pattern.findall(line)
        if matches:
            for match in matches:
                image_filename = match
                image_path = os.path.join(output_folder, image_filename)
                if os.path.exists(image_path):
                    image_markdown = f"![image]({image_path})"
                    line = line.replace(f'[{image_filename}]', image_markdown)
        new_lines.append(line)

    with open(markdown_path, "w") as md_file:
        md_file.writelines(new_lines)

Step 6: Convert Markdown to HTML

Finally, convert the Markdown to HTML:

from markdown import markdown
def convert_markdown_to_html(markdown_path, html_output_path):
   
   html = markdown(open(markdown_path, 'r', errors='ignore').read())

   with open(html_output_path, 'w') as html_file:
        html_file.write(html)

Conclusion

Converting PDFs to HTML is essential for maintaining the structure and helping AI models understand the content better. While you can build your own code as demonstrated, creating generative AI applications often requires multiple tools that need modification.

Best Prompt Engineering Techniques Part 3

Prasanth Sai
June 20, 2024

We explored the most widely used prompt engineering techniques in the first and second part of this series. As prompt engineers continue to experiment and innovate, we’ve identified additional effective and popular techniques emerging from the prompt engineering community. In this third part, we will cover the following:

  • Active Prompt
  • Tree of Thoughts Prompting
  • Multimodal CoT
  • Reflexion
  • Directional Stimulus Prompting

Active Prompt

Active Prompting is a refined approach to implementing Chain of Thought (CoT) prompting. A key issue with CoT prompting is that the examples provided are dependent on human input, which might not always be optimal. The question then becomes: how do we ensure the examples used in CoT are effective enough to yield accurate answers? To address this, Diao et al., (2023) introduced the ‘active prompting’ technique.

Steps Involved:

  • Create a List of Training Questions:
    • Examples:
      • Karen is packing her backpack for a long-distance hike. She has 10 items to fit in, but only room for 7. How many items will she leave behind?
      • A robe takes 2 bolts of blue fiber and half that much white fiber. How many bolts in total does it take?
      • Josh decides to try flipping a house. He buys a house for $200,000 and spends $50,000 on renovations. If he sells the house for $300,000, what is his profit?
      • Liam has a garden with 12 different types of flowers. He decides to plant an equal number of each type in 3 different rows. How many flowers will be in each row?
      • Mia is organizing a bookshelf that can hold 60 books. She already has 35 books and buys 20 more. How many more books can she add to the shelf?
      • Sam is preparing for a marathon. He runs 5 miles a day for 6 days a week. How many miles will he run in 4 weeks?
      • A bakery sells cupcakes in boxes of 8. If a customer buys 5 boxes, how many cupcakes do they have?
  • Use Normal CoT Prompting:
    • Select a few questions and use CoT prompting to generate answers for each question, excluding the chosen input.
  • Repeat k Times and Calculate Uncertainty Scores:
    • For instance, repeat the process five times for each question to obtain k answers.
    • Determine the uncertainty score based on the k answers (5 answers in this example).
  • Sort Questions:
    • Arrange all questions in descending order based on their uncertainty scores.
  • Annotate Top Questions:
    • Choose the top 2 or 3 questions and have humans annotate them, providing the actual steps for these questions.
  • Use Annotated Pairs:
    • Input these human-annotated question-and-answer pairs into your CoT prompting to generate answers.

Tree of Thoughts Prompting

Tree of Thoughts (ToT) Prompting, introduced by Shunyu Yao et al. in 2023, provides a structured roadmap for guiding AI models to generate comprehensive responses.

Visualizing the ‘Tree of Thoughts’ Concept:

Think of a tree’s structure: a solid trunk represents the main topic, and as it branches out, each branch represents a more specific aspect or query related to the main topic.

Tree of Thoughts prompting

Components:

  1. The Core Foundation (Trunk):
    • This initial prompt sets the foundation and provides direction and context for subsequent prompts.
  2. Branching Out (Subtopics and Related Ideas):
    • These are follow-up questions or sub-topics stemming from the primary prompt, adding depth and clarity.

Example:

Dave Hulbert’s Repo 2023 demonstrated using ToT to solve a riddle. ChatGPT 3.5 initially struggled but performed better with a ToT format.

Game Example:

To illustrate the ToT technique, consider the game of 24 puzzle. The goal is to calculate the number 24 using the input set “4 5 6 10”. Here’s a solution:

  1. Step 1:
    • Generate — The model generates eight possible proposals for the first step, e.g., 10 – 4 = 6 (remaining: 5, 6, 6).
    • Evaluate — The model evaluates each proposal three times and sums the scores.
    • Select — The model selects the best five proposals based on their evaluation scores.
  2. Step 2:
    • Generate — For each of the five nodes, the model generates eight possible proposals for the second step, e.g., 5 * 6 = 30 (remaining: 6, 30).
    • Evaluate — The model evaluates each proposal.
    • Select — The model selects the best five proposals to form the second layer of the tree.
  3. Step 3:
    • Generate — For each selected node, the model generates eight possible proposals for the third step, e.g., 30 – 6 = 24 (remaining: 24).
    • Evaluate — The model evaluates each proposal.
    • Select — The model selects the best proposals for the next layer.
  4. Step 4:
    • Generate — For each proposed solution that correctly solves the puzzle, a formal answer is generated in the desired format.

Thus, the answer is (5×(10−4))−6=24(5 \times (10 – 4)) – 6 = 24(5×(10−4))−6=24.

Multimodal CoT

Multimodal CoT enhances reasoning in Large Language Models (LLMs) by incorporating both text and images.

Two-Stage Framework:

  1. Rationale Generation:
    • Combines language and vision inputs to generate intermediate reasoning steps.
  2. Answer Inference:
    • Uses the rationale from the first stage along with the original vision input to infer the final answer.
Multimodal CoT

Reflexion

Reflexion mirrors human intelligence by allowing AI to learn from its mistakes. This iterative problem-solving method is particularly useful in fields without a definitive ground truth.

Technique:

In GPT-4, Reflexion involves analyzing mistakes, learning from them, and improving performance through a self-contained loop. This approach enhances the AI’s ability to solve complex tasks by using feedback to refine strategies continuously.

Directional Stimulus Prompting

This technique involves adding a small hint or help in the initial prompt to guide the model towards the desired output. By steering the model’s thinking in a specific direction, it better understands and delivers the expected results.

Conclusion

In this part of our series, we’ve explored advanced prompt engineering techniques that can significantly enhance the performance of AI models. Techniques like Active Prompt, Tree of Thoughts Prompting, Multimodal CoT, Reflexion, and Directional Stimulus Prompting represent the cutting edge of prompt engineering. As the field of prompt engineering continues to evolve, these innovative approaches will push the boundaries of what AI can achieve, driving better outcomes in various applications.

By understanding and applying these techniques, prompt engineers can create more effective and accurate AI models, ultimately improving the capabilities of AI systems. Embracing these advanced prompt engineering techniques will ensure that AI continues to grow smarter and more efficient, meeting the ever-increasing demands of users and applications.

Leveraging AI for personalization can significantly enhance your efforts, ensuring your messages resonate with your audience at the right time and through the right channels. This article explores how AI can revolutionize your marketing and sales campaigns by personalizing content to meet each customer’s unique needs.

What is a Business Campaign?

A business campaign is a coordinated effort to achieve specific goals such as increasing brand awareness, generating leads, boosting sales, or promoting special offers. Key components include:

  1. Objectives: Clear, measurable goals (e.g., increase sales by 10%).
  2. Target Audience: The campaign aims to reach a specific group of people.
  3. Messaging: Compelling messages that resonate with the audience.
  4. Channels and Tactics: Platforms and methods used to deliver messages (e.g., social media, email, print).
  5. Budget and Resources: Allocation of funds and materials needed.
  6. Timeline: Schedule of activities and milestones.
  7. Execution: Implementing the planned activities.
  8. Monitoring and Adjustment: Tracking performance and making real-time adjustments.
  9. Evaluation and Reporting: Analyzing results against objectives and compiling a report.

By effectively planning and executing these steps, businesses can engage their audience, achieve their marketing goals, and meet sales targets.

Marketing Campaigns vs. Sales Campaigns

Marketing Campaigns

Marketing campaigns focus on building brand awareness, generating interest, and nurturing leads. They use channels like social media, content marketing, email marketing, and advertising to reach a broad audience and create a positive brand image. The goal is to attract potential customers and guide them through the buyer’s journey.

Sales Campaigns

Sales campaigns are more directly focused on driving immediate sales and conversions. They often involve promotions, discounts, limited-time offers, and direct outreach to potential customers. Sales campaigns aim to close deals, increase revenue, and meet specific sales targets within a set timeframe.

Both types of campaigns are essential for a comprehensive business strategy, with marketing campaigns laying the groundwork for sales efforts and sales campaigns capitalizing on the interest generated by marketing activities.

The Power of Personalization

The ideal way of personalization is when a campaign reaches the user with the right content based on their needs and preferences, through the right channel, at the right time. Ideally, if businesses have infinite time then they can identify dynamic customer segments, analyzing each user profile and their activities, and crafting specific content tailored to each user.

AI-driven personalization makes this possible by automating the process of adding personalization at each user profile level. This ensures that the content type and message align with the user profile and business goals.

Personalization in Marketing Campaigns

Example Scenario: Promoting a New Sneaker Brand

Marketing heads might want to promote specific product categories during certain seasons based on user activities. For instance, to promote a new sneaker brand launch, you can create a marketing campaign using GPT models with an AI Agent and tool framework. Give the following input to the LLM models:

  1. Define the Persona: Include the demographics of the target user.
  2. Specify the Product: Detail the product, images, and the corresponding brand message.
  3. Brand Tone: Define the brand tone.
  4. User Data: Provide user profile data, purchase data, user journey events data on the website, and previous campaign behavior.
  5. Target Audience Volume: Determine the maximum number of users to target.

For example, you want to promote new sneakers to existing users via email. The sneakers come in various styles like colorful, classic, knee-length, and ankle-length. The brand message is “Sneakers with style and comfort,” targeting users interested in sneakers, either young individuals or parents buying for their children. The campaign aims to target 50,000 users.

Step 1: Segmenting the Audience

The AI model outputs potential segments, ensuring the total users in each segment sum up to 50,000. The marketing rep can review and adjust these segments. For example:

  • Segment 1: Users who purchased colorful sneakers at least 4 months ago.
  • Segment 2: Users who purchased classic color sneakers at least 4 months ago.
  • Segment 3: Users aged 20-32 who purchased shoes 6 months ago (excluding users in Segment 1 and 2).
  • Segment 4: Users aged 33-39 who purchased shoes at least 4 months ago (excluding the users in Segment 1 and 2)

Step 2: Personalizing the Content

After receiving “go ahead” from human on Step 1, the model recommends and creates content tailored to each segment and, if feasible, unique personalized content for individual users based on their journey on the website or app.

Content Examples:

  • Segment 1 & 3: Vibrant images of colorful sneakers with graffiti-style backgrounds and content.
  • Segment 2 & 4: Visuals of classic sneakers with business casual backgrounds and similar message.

Deeper User-Specific Example within Segment 1

Let’s consider Alex, a user in Segment 1:

  • Name: Alex
  • Age: 25
  • Gender: Male
  • Location: New York City
  • Purchase History: Purchased colorful sneakers 5 months ago

The Ultimate Guide on Retrieval Strategies – RAG (part-4)

Prasanth Sai
December 28, 2023

Overview:

Retrieval-augmented generation (RAG) has revolutionized how we interact with large datasets and corpus of information. At its core, the retrieval process in RAG is about sourcing relevant external data to enhance response generation. This external integration allows models to produce responses that are not just accurate and detailed, but also contextually richer, especially for queries needing specific or current knowledge.

In this guide, we’ll explore various retrieval methods, breaking down complex concepts into digestible parts, and ensuring you get the most out of RAG’s potential. Please note this is a continuation of the RAG article part 3

Retrieval Methods

1. Search Methods

1.1 Vector Store Flat Index

Basic Retrieval

The heart of RAG is the search index, where content is stored in vectorized form. The simplest form is a flat index, leveraging metrics like cosine similarity to measure the likeness between query vectors and content vectors. This method is highly popular for its straightforward approach to determining similarity.

Cosine similarity measures the cosine of the angle between two vectors in a multi-dimensional space. It essentially assesses how similar the directions of two vectors are. The value ranges from -1 to 1, where 1 means exactly the same direction (highly similar), 0 indicates orthogonality (no similarity), and -1 indicates completely opposite directions. We calculate similarity scores between user vector query and with each vector chunk and then extract top-k similar chunks.

1.2 Hierarchical Indices

Hierarchical Indices

For larger document sets, a two-step approach is effective. Create one index for summaries and another for document chunks. This method allows for rapid filtering of relevant documents through summaries before diving into detailed searches within selected documents.

1.3 Hypothetical Questions and HyDE

The proposed method involves an LLM (Large Language Model) generating specific questions for each text chunk, which are then converted into vector form. During a search, queries are matched against this index of question vectors instead of the traditional chunk vectors. This enhances search quality, as the semantic similarity between the query and the hypothetical question tends to be higher than with a regular text chunk.

Furthermore, an alternative approach, dubbed HyDE (Hypothetical Direct Embedding), reverses this logic. Here, the LLM generates a hypothetical response based on the query. The vector of this response, combined with the query vector, is used to refine and improve the search process, ensuring more relevant and accurate results.

1.4 Small to Big Retrieval

This technique involves linking smaller data chunks to their larger parent chunks. When a relevant smaller chunk is identified, the corresponding larger chunk is retrieved, providing a broader context for the Large Language Model (LLM). This method includes the ‘Parent Document Retriever’ and ‘Sentence Window Retrieval,’ each focusing on expanding the context for more grounded responses.

1.4.1 Parent Document Retriever
parent document retriever method

Begin by retrieving smaller segments of data that are most relevant to answering a query, then use their associated parent identifiers to access and return the larger parent chunk of data that will be passed as context to the LLM (Large Language Model).

1.4.2 Sentence window retrieval

Sentence Window Retrieval involves initially retrieving a specific sentence that is most relevant to answering a query and then returning a broader section of text that surrounds this sentence to give the LLM a much wider context to ground its responses. This is the same as Parent Document Retriever just that instead of chunks of text it is sentence chunks and expansion is a window above and below the sentence.

sentence window expansion

1.5 Fusion Retrieval

This approach combines traditional keyword-based search methods (like tf-idf or BM25) with modern semantic searches. The key here is integrating different retrieval results using algorithms like Reciprocal Rank Fusion for a more comprehensive output.

2. Reranking and Filtering

Post-retrieval, results undergo refinement through methods like filtering and re-ranking. Using tools like LlamaIndex’s Postprocessors, you can filter based on similarity scores, keywords, metadata, or re-rank using models like LLMs, sentence-transformer cross-encoders, or Cohere’s reranking endpoint.

3. Query Transformation

LLMs can be utilized to modify user queries for improved retrieval. This includes decomposing complex queries into simpler sub-queries or employing techniques like step-back prompting and query re-writing for enhanced context retrieval.

  1. Step-back prompting uses LLM to generate a more general query, retrieving for which we obtain a more general or high-level context useful to ground the answer to our original query.
    Retrieval for the original query is also performed and both contexts are fed to the LLM on the final answer generation step.
  2. Query re-writing uses LLM to reformulate the initial query to improve retrieval

4. Query Routing

Query routing is the decision-making step, determining the next course of action based on the user query. This could mean summarizing, searching a data index, or experimenting with different routes for a synthesized response. It also involves selecting the appropriate index or data store for the query using LLMs.

Conclusion

While there are other methods like reference citations and chat engines, the focus here is on those most applicable to production scenarios. Although some, like Agent RAG, offer intriguing possibilities, they may not yet be suitable for production environments due to their slower processing and higher costs. 
Retrieval methods in RAG are dynamic and continually evolving. By understanding and applying these strategies, one can significantly enhance the capability of LLMs, leading to more accurate, relevant, and context-rich responses.

In the next part of this series, we see the end-to-end implementation of the RAG module using Llamaindex and Supabase as our vector database.

The Ultimate Guide on Chunking Strategies – RAG (part 3)

Prasanth Sai
December 26, 2023

Overview

Chunking in Large Language Model (LLM) applications breaks down extensive texts into smaller, manageable segments. This technique is crucial for optimizing content relevance when embedding content in a vector database using LLMs. This guide will explore the nuances of effective chunking strategies. This is part 3 of the RAG series and check part-1 and part-2 to understand the overall RAG pipeline effectively.

Why Chunking is Necessary

  • LLMs have a limited context window, making it unrealistic to provide all data simultaneously.
  • Chunking ensures that only relevant context is sent to the LLM, enhancing the efficiency and relevance of the responses generated.

Considerations Before Chunking

Document Structure and Length

  • Long documents like books or extensive articles require larger chunk sizes to maintain sufficient context.
  • Shorter documents such as chat sessions or social media posts benefit from smaller chunk sizes, often limited to a single sentence.

Embedding Model

The chunk size selected often dictates the type of embedding model used. For instance, sentence transformers are well-suited to sentence-sized chunks, whereas models like OpenAI’s “text-embedding-ada-002” may be optimized for different sizes.

Expected Queries

  • Shorter queries typically require smaller chunks for factual responses.
  • More in-depth questions may necessitate larger chunks to provide comprehensive context.

Chunk Size Considerations

  • Small chunk sizes, like single sentences, offer accurate retrieval for granular queries but may lack sufficient context for effective generation.
  • Larger chunk sizes, such as full pages or paragraphs, provide more context but may reduce the effectiveness of granular retrieval.
  • An excessive amount of information can decrease the effectiveness of generation, as more context does not always equate to better outcomes.

Chunking Methods

Naive Chunking

  • Involves chunking based on a set number of characters.
  • Fast and efficient but may not account for the structure of the data, such as headers or sections.

Naive Sentence Chunking

  • Splits text based on periods.
  • Not always effective, as periods may appear within sentences and not necessarily at the end.

NLP Driven Sentence Splitting

Utilizes natural language processing tools like NLTK or Spacy to chunk sentences more effectively, considering linguistic structures.

Recursive Character Text Splitter

Recursively splits text into chunks based on set sizes and text structure, keeping paragraphs and sentences intact as much as possible.

Structural Chunkers

  • Splits HTML and markdown files based on headers and sections.
  • Chunks are tagged with metadata specifying their headers and sub-sections, aiding in content organization.

Summarization Chains

  • Involves summarizing each document and sending these summarizations into the context.
  • For long summaries, methods like ‘Map reduce’ are used, where the document is chunked, and each chunk is summarized separately before combining all summaries into one.
  • The ‘refine’ method is another approach where the overall summary is iteratively updated based on each chunk.

Chunking Decoupling (Small to Big)

  • Summary chunks are tagged with the original file link in their metadata.
  • When a summary is retrieved, the corresponding full document can be injected into the context instead of just the summary.
  • This method can also be applied to sentence chunks, allowing for expansion to relevant snippets or the entire document based on the context length and document size.

Conclusion

This article marks another step in our journey through the RAG pipeline using Large Language Models. As we wrap up, stay tuned for Part 4 of our series, which will focus on the Retriever – the heart of the RAG system. This upcoming piece will offer an in-depth look at the pivotal component that enhances the pipeline’s efficiency and accuracy, further illuminating the intricate workings of these advanced models.
