In the rapidly evolving landscape of artificial intelligence, CIOs face the constant challenge of leveraging technology to maintain a competitive edge. Microsoft’s introduction of Retrieval Augmented Generation (RAG) within Azure AI Search represents a significant stride in enhancing Large Language Models (LLMs) like ChatGPT. This technology augments LLM capabilities by integrating an information retrieval system, providing a robust framework for businesses to refine AI-generated responses using their proprietary data.
Strategic Importance of RAG for Businesses
RAG architecture enables businesses to constrain generative AI applications to utilize enterprise-specific content, including vectorized documents and images. This is particularly crucial for enterprises looking to maintain the relevance and accuracy of AI-generated content. The core of RAG’s value proposition lies in its ability to dynamically retrieve and utilize relevant information from a vast repository of enterprise data, ensuring that the AI’s responses are both grounded and contextually aware.
Azure AI Search: A Comprehensive Solution for Information Retrieval
Azure AI Search emerges as a formidable solution in the RAG architecture, offering advanced indexing strategies, query capabilities, and relevance tuning. Its infrastructure guarantees security, global reach, and reliability, essential for enterprise operations. This platform not only supports embedding models for indexing but also seamlessly integrates with chat models and language understanding models for retrieval, making it an all-encompassing solution for businesses aiming to enhance their AI capabilities.
Question answering using Retrieval Augmented Generation with foundation models in Amazon SageMaker JumpStart
In the RAG framework, external data can be sourced from a variety of repositories, including document stores, databases, or external APIs. The initial step involves transforming both the documents and the user’s query into a format that allows for effective comparison and relevance determination. To facilitate this, both the document collection (acting as a knowledge library) and the user’s query are converted into numerical representations through the use of embedding language models. These embeddings serve as numerical vectors that encapsulate the concepts contained within the text. Following this, the embedding of the user’s query is used to locate pertinent text within the document collection via a similarity search within the embedding space. The text identified as relevant is then concatenated with the user’s initial prompt, enriching the context for the Large Language Model (LLM). With the inclusion of relevant external data in the context, the LLM generates responses that are both pertinent and precise.
To use the JumpStart notebooks in SageMaker companies can use it as is or customize them to their needs. To customize, organizations can use your own set of documents in the knowledge library, use other relevancy search implementations like OpenSearch, and use other embedding models and text generation LLMs available on JumpStart.
Custom RAG Pattern: A Blueprint for Advanced AI Interactions
The custom RAG pattern in Azure AI Search involves a sequence of actions starting from the user’s query to generating a response through the LLM. Azure AI Search acts as the intermediary, retrieving relevant information based on the query and supplying it to the LLM. This approach does not require additional training for the LLM, as it leverages pre-trained models augmented with enterprise-specific data, ensuring responses are both accurate and contextually relevant.
n a RAG pattern, queries and responses are coordinated between the search engine and the LLM. A user’s question or query is forwarded to both the search engine and to the LLM as a prompt. The search results come back from the search engine and are redirected to an LLM. The response that makes it back to the user is generative AI, either a summation or answer from the LLM.
There’s no query type in Azure AI Search – not even semantic or vector search – that composes new answers. Only the LLM provides generative AI. Here are the capabilities in Azure AI Search that are used to formulate queries:Expand table
| Query feature | Purpose | Why use it |
|---|---|---|
| Simple or full Lucene syntax | Query execution over text and nonvector numeric content | Full text search is best for exact matches, rather than similar matches. Full text search queries are ranked using the BM25 algorithm and support relevance tuning through scoring profiles. It also supports filters and facets. |
| Filters and facets | Applies to text or numeric (nonvector) fields only. Reduces the search surface area based on inclusion or exclusion criteria. | Adds precision to your queries. |
| Semantic ranking | Re-ranks a BM25 result set using semantic models. Produces short-form captions and answers that are useful as LLM inputs. | Easier than scoring profiles, and depending on your content, a more reliable technique for relevance tuning. |
| Vector search | Query execution over vector fields for similarity search, where the query string is one or more vectors. | Vectors can represent all types of content, in any language. |
| Hybrid search | Combines any or all of the above query techniques. Vector and nonvector queries execute in parallel and are returned in a unified result set. | The most significant gains in precision and recall are through hybrid queries. |
Azure AI Search: Enabling a Wide Array of Content
Azure AI Search’s capability to index and retrieve a diverse range of content types, from text to images, using various features such as OCR and Image Analysis, sets it apart. This versatility ensures that enterprises can leverage their entire corpus of data, irrespective of format, to enhance the AI’s responses.
| Content type | Indexed as | Features |
|---|---|---|
| text | tokens, unaltered text | Indexers can pull plain text from other Azure resources like Azure Storage and Cosmos DB. You can also push any JSON content to an index. To modify text in flight, use analyzers and normalizers to add lexical processing during indexing. Synonym maps are useful if source documents are missing terminology that might be used in a query. |
| text | vectors 1 | Text can be chunked and vectorized externally and then indexed as vector fields in your index. |
| image | tokens, unaltered text 2 | Skills for OCR and Image Analysis can process images for text recognition or image characteristics. Image information is converted to searchable text and added to the index. Skills have an indexer requirement. |
| image | vectors 1 | Images can be vectorized externally for a mathematical representation of image content and then indexed as vector fields in your index. You can use an open source model like OpenAI CLIP to vectorize text and images in the same embedding space. |
