Vector databases are specialized data storage systems designed to handle, store, and search high-dimensional vector data. These vectors are often generated by machine learning models to represent complex data like images, audio, video, and especially text, including embeddings from natural language processing (NLP) tools like OpenAI, BERT, or SentenceTransformers.
Unlike traditional databases that store and retrieve data using exact match queries, vector databases allow for similarity searches based on mathematical distance between vectors. This enables more accurate and intelligent search and recommendation systems.
What Are Vector Databases Used For?
Vector databases are commonly used in AI-driven applications that require fast and accurate search through unstructured data. Typical use cases include:
-
Semantic Search: Search engines that return results based on meaning rather than keyword matching.
-
Recommendation Systems: Matching users with content, products, or services based on vector similarity.
-
Image and Video Recognition: Finding visually similar assets or identifying objects in media.
-
Natural Language Processing: Powering chatbots, question answering, and intent matching.
-
Anomaly Detection: Identifying unusual patterns in time series, behavior, or activity data.
