Beyond Keywords Image similarity search in Azure Cosmos DB for PostgreSQL Python Data Science Day (Дата оригинальной публикац
Vector search, also known as vector similarity search, is a method that helps you find similar items based on their content rather than exact matches on properties like keywords, tags, or other metadata, as keyword-based search systems do. It leverages machine learning to capture the meaning of data, allowing you to find similar items based on their content. The key idea behind vector search is the translation of unstructured data, such as text, images, videos, and audio, into high-dimensional vectors (also known as embeddings) and the application of nearest neighbor algorithms to find similar data.
In this quickstart session, we will work together to build an image similarity search system utilizing Python, Azure Cosmos DB for PostgreSQL, and pgvector, an open-source vector similarity search extension for PostgreSQL. We will explore the process of generating vector embeddings using the Azure AI Vision multi-modal embeddings API and enabling the pgvector extension. We will then discuss the exact and approximate nearest neighbor search and use Azure Cosmos DB for PostgreSQL for storing and querying vector data.
