embedding
What It Means
An embedding is a way of representing complex information (like words, images, or documents) as numerical vectors that capture the essential relationships and meaning of the original data. Think of it as translating human concepts into a mathematical language that computers can understand and work with, while preserving what makes those concepts similar or different from each other.
Why Chief AI Officers Care
Embeddings are the foundation of most modern AI systems including search, recommendation engines, and large language models - poor quality embeddings directly impact AI performance and business outcomes. They also create significant intellectual property considerations since embedded representations of proprietary data can inadvertently leak sensitive business information or create vendor lock-in scenarios.
Real-World Example
When Netflix recommends movies, it converts each film into an embedding vector based on genre, cast, plot elements, and viewer behavior - movies with similar vectors (like action films with the same lead actor) end up close together in the mathematical space, enabling the system to suggest 'Top Gun: Maverick' to someone who liked 'Mission Impossible' without explicitly programming that connection.
Common Confusion
People often think embeddings are just simple similarity scores or tags, but they're actually high-dimensional mathematical representations that can capture subtle, non-obvious relationships that humans might miss. They're also frequently confused with feature engineering, though embeddings are learned automatically rather than manually designed.

Technical Definitions
NISTNational Institute of Standards and Technology
"An embedding is a representation of a topological object, manifold, graph, field, etc. in a certain space in such a way that its connectivity or algebraic properties are preserved. For example, a field embedding preserves the algebraic structure of plus and times, an embedding of a topological space preserves open sets, and a graph embedding preserves connectivity. One space X is embedded in another space Y when the properties of Y restricted to X are the same as the properties of X. "Source: wolfram_math_2022
