CORE DEFINITION

Represent multiple features of an object as a vector form—each dimension corresponds to a feature. Scaffold role: mathematical representation of multiple features. Vector representation allows features to undergo mathematical operations.

SCAFFOLDING EFFECT

Anchor fast decisions

If matrix A acting on a non-zero vector x only scales it without changing its direction, i.e., Ax = λx, then x is an eigenvector and λ is an eigenvalue. The mechanism is spectral decomposition.

Curse of Dimensionality

The curse of dimensionality refers to various phenomena that arise when analyzing and organizing data in high-dimensional spaces that do not occur in low-dimensional settings such as the three-dimensional physical space of everyday experience. The expression was coined by Richard E. Bellman when considering problems in dynamic optimization.

Gabriel's Horn

Gabriel's horn (also called Torricelli's trumpet) is a type of geometric figure that has infinite surface area but finite volume. The name refers to the Christian idea that the archangel Gabriel will one day blow his horn to announce Judgment Day. The properties of this figure were first studied by …
