This post shows you how to set up RAG using DeepSeek-R1 on Amazon SageMaker with an OpenSearch Service vector database as the knowledge base. You will create a connector to SageMaker with Amazon Titan Text Embeddings V2 to create embeddings for a set of documents with population statistics. Examine the code in run_rag.py.

OpenSearch Service allows you to store vectors and other data types in an index, and offers rich functionality that allows you to search for documents using vectors and measuring the semantical relatedness, which we use in this post. Using the k-nearest neighbors (k-NN) algorithm, you define how many images to return in your results.

These included document translations, inquiries about IDIADAs internal services, file uploads, and other specialized requests. This approach allows for tailored responses and processes for different types of user needs, whether its a simple question, a document translation, or a complex inquiry about IDIADAs services.

We stored the embeddings in a vector database and then used the Large Language-and-Vision Assistant (LLaVA 1.5-7b) 7b) model to generate text responses to user questions based on the most similar slide retrieved from the vector database. The OSI pipeline ingests the data as documents into an OpenSearch Serverless index.

Home Table of Contents Approximate Nearest Neighbor with Locality Sensitive Hashing (LSH) What Is Locality Sensitive Hashing (LSH)? Another example is in the field of text document similarity. Imagine you have a vast library of documents and want to identify near-duplicate documents or find documents similar to a query document.

We use OpenSearch Serverless as a vector database for storing embeddings generated by the Titan Multimodal Embeddings model. In the user interaction phase, a question from the user is converted into embeddings and a similarity search is run on the vector database to find a slide that could potentially contain answers to user question.

Key Components of Data Science Data Science consists of several key components that work together to extract meaningful insights from data: Data Collection: This involves gathering relevant data from various sources, such as databases, APIs, and web scraping. Data Cleaning: Raw data often contains errors, inconsistencies, and missing values.

Databases to be migrated can have a wide range of data representations and contents. For the sake of argument, let’s ignore the fact that the use of such data types in databases is justified only in a few specific cases, as this problem often arises when migrating complex systems. in XML, CLOB, BLOB etc.
