Embedding
A. What is Embedding
A numeric vector that captures the meaning of text or an image. It powers “vector search,” which finds and classifies items by semantic similarity.
An embedding converts the meaning of text, images and other content into a high-dimensional numeric vector. The closer two things are in meaning, the closer they are placed in the vector space.
This property enables vector search, which matches by semantic similarity rather than exact keyword matches. It is widely used in the retrieval part of RAG and for discovering similar documents.
