This ppt contains slides from the original presentation by Karel Lenc, Andrea Vedaldi
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.
