Tīmeklis2024. gada 27. marts · It is well known that the L 2 norm is not differentiable at the origin (consider x ↦ x , for instance). It is not clear either what is meant by 'local equivalence' of norms.

L1 and L2 distances are equivalently known as L1/L2 norms (of the differences between a pair of images). The L2 distance is much more unforgiving than the L1 distance when it comes to differences between two vectors. i.e, the L2 distance prefers many medium disagreements to one big one. k-Nearest … dpgr privacy https://wilhelmpersonnel.com
