THREE KEY MATHEMATICAL PROPERTIES OF

REPRESENTATIONS • Equivariance studies how transformations of the

input image are encoded by the representation.

• Invariance is a special case where a transformation has no effect [on the representation].

• Equivalence studies whether two heterogeneous representations capture the same visual information.
