Meaningful neighborhoods and the unclassified remainder

What counts as a meaningful region of a representation space, and what remains outside the regions a system can recognize?

Formülasyon

Face, person, and expression are proposed as overlapping meaning regions. Narrower categories can increase discrimination, while the status of noise or meaningless dimensions remains unsettled.

Gerilim

An interpretable region need not be a mathematical manifold; a classifier covering the space need not make everything meaningful.

Açık soru

How could a system encounter a case for which its existing meaning regions are inadequate?
