Dimensionality

That is to say, it is the Analogue of Space, not in the sense in which we formerly regarded Space as the negation of Matter; but in the sense of Infinite Dimensionality, or of Dimensionality in all directions, as a vague generalization from the three spatial dimensions Length, Breadth, and Thickness.

This often happens, for example, when a two-dimensional solution is obtained for data whose appropriate dimensionality is higher.

Finite Dimensionality of de Rham Cohomology: Proposition 5.3.1. If the manifold M has a finite good cover, then its cohomology is finite dimensional.

As well as the low dimensionality of the Bloch electron states, […]

The difficulties in implementing classification algorithms as is, on high volume databases, derives from the increase in the number of records/instances in the database and of attributes/features in each instance (high dimensionality).

The programming language does not impose any restrictions on the dimensionality of the arrays.

A vector v=(22,38,52,12) defines a four-dimensional space with a point at the stated co-ordinates, and so on to any dimensionality n. Vector spaces of dimensionality greater than three are impossible to visualise directly […]
