A Vector Database (Vector DB) is a specialized type of database designed to handle vector embeddings. These embeddings are numerical representations of data points, such as text, images, audio, or video, generated using machine learning models. Vector databases enable efficient storage, indexing, and querying of these high-dimensional vectors, making them crucial for applications involving similarity search, recommendation systems, and AI-powered data retrieval.
Key Features of Vector DB:
- High-Dimensional Data Support: Vector databases are optimized for storing and managing vectors with hundreds or thousands of dimensions.
- Similarity Search: They support nearest neighbor search (NNS) or approximate nearest neighbor (ANN) search, which allows finding data points similar to a given query vector.
- Scalability: Designed to scale horizontally, they handle large datasets and ensure low-latency query responses.
- Integration with AI Models: Commonly integrated with models like OpenAI’s ChatGPT, BERT, or image recognition models to process embeddings and provide meaningful search results.
