A Quick Guide to RAG Using Algoboost for Embedding Vector Inference

In the evolving landscape of artificial intelligence and machine learning, enhancing the quality of generated content has always been a paramount goal. One innovative approach that has gained significant traction is Retrieval Augmented Generation (RAG). RAG combines the strengths of retrieval-based systems and generation-based models to produce more accurate, contextually rich, and informative outputs. This blog will introduce you to RAG and demonstrate how Algoboost, an app specializing in embedding vector inference and vector embedding storage via API, plays a crucial role in this paradigm.

Understanding Retrieval Augmented Generation

The RAG process typically involves two main components:

• Retriever: This component searches a database of embeddings to find the most relevant pieces of information related to the input query. These embeddings are precomputed vectors that represent the semantic content of various documents or data points.

• Generator: After retrieving relevant information, the generator uses this context to produce a well-informed response. The additional context helps the generator to produce outputs that are not only contextually appropriate but also factually accurate.

The Role of Algoboost in RAG

Algoboost is a powerful tool designed to facilitate embedding vector inference and vector embedding storage via API. It seamlessly integrates with the RAG framework, providing essential functionalities that enhance the retrieval and generation process.

Embedding Vector Inference

Embedding vector inference is the process of converting text data into fixed-size numerical vectors that capture the semantic meaning of the data. Algoboost excels in this domain by providing robust API endpoints that allow users to infer embeddings from their text data efficiently. These embeddings serve as the foundation for the retrieval process in RAG.

Vector Embedding Storage

Once embeddings are generated, they need to be stored in a manner that allows for efficient retrieval. Algoboost offers a sophisticated storage solution for vector embeddings, ensuring that the retrieval process is both fast and scalable. By using Algoboost’s API, developers can store vast amounts of embeddings and retrieve them quickly when needed, facilitating the smooth operation of RAG systems.

• Retrieve Relevant Documents

The next step is to retrieve relevant documents based on a query. This involves converting the query into an embedding vector and then retrieving similar embeddings from the storage.

from transformers import GPT2LMHeadModel, GPT2Tokenizer

# Replace 'YOUR_ALGOBOOST_API_KEY' with your actual AlgoBoost API key

    }

    # Set the request headers with the API key
    headers = {
        "Authorization": f"Bearer {ALGOBOOST_API_KEY}"
    }

    try:
        # Make a POST request to the API with form data and files
        response = requests.post(
            f"https://app.algoboost.ai/api/model/similarity/{model}/{endpoint}",
            headers=headers,
            data=form_data,
        )

        # Check the HTTP status code
        if response.status_code == 200:
            # Parse the JSON response
            results = response.json()
            return results
        else:
            print(f"API request failed with status code: {response.status_code}")
            return None

    except Exception as e:
        print(f"An error occurred: {str(e)}")
        return None

• Output return json of top results and respective vector ids which you can use to fetch the original text

{
    "results": {
        "distance": [
            0.9669929146766663,

    }
    content = []

    for url in content_urls:
        try:
            response = requests.post(
                url["content_url"],
                headers=headers,
            )

            if response.status_code == 200:
                # Parse the JSON response
                results = response.json()
                content.append(results)

                return None
        except Exception as e:
            print(f"An error occurred: {str(e)}")

    return content

• Generate Responses

Use a generative model to produce a response based on the retrieved documents.

import requests
from transformers import GPT2LMHeadModel, GPT2Tokenizer

# Initialize the model and tokenizer
model_name = 'gpt2'  # Or any other generation model you prefer
tokenizer = GPT2Tokenizer.from_pretrained(model_name)
generator_model = GPT2LMHeadModel.from_pretrained(model_name)

def generate_response(retrieved_documents):
    """
    Generate a response using a generation model and retrieved documents.

    Args:
        query (str): The input query.
        retrieved_documents (list): List of retrieved documents.

    Returns:
        str: Generated response.
    """
    context = " ".join(retrieved_documents)
    input_text = f"Context: {context} Query: {query}"

    inputs = tokenizer.encode(input_text, return_tensors='pt')
    outputs = generator_model.generate(inputs, max_length=300, num_return_sequences=1)

    response = tokenizer.decode(outputs[0], skip_special_tokens=True)
    return response

Output

Context: Machine learning algorithms are used to analyze large datasets efficiently. Artificial intelligence can detect patterns in data that humans might miss. Artificial intelligence is transforming the way we interact with technology. Artificial intelligence assists in automating repetitive tasks. Query: What are the benefits of machine learning in data analysis?
