space

Definition

A mathematical space in which representations, parameters, or actions live — latent space, embedding space, parameter space, search space. Invoking the word implies that geometry carries meaning: distances correspond to similarity, and directions can encode attributes. It is an abstract set with a notion of dimension and distance, not a location.
