Questions about L2 Normalization #13
Comments
Hi @tamerthamoqa |
Hello riverHu233, My interpretation might be incorrect, but according to the facenet paper (description of figure 1) it implies that the squared l2-norm space might be [0, 4] though please keep in mind I am not sure about this since I haven't looked too deeply into this matter. There are discussion threads about this topic in the David Sandberg 'facenet' github repository but I haven't found a clear answer, at least, from what I remember. From what I have seen, all pytorch implementations of facenet on github use the same threshold range so that is the main reason why I went with that range, but to be honest, I need to look into it to get a clearer understanding myself. |
Hi @tamerthamoqa ,
, so the maximum distance of two features in feature space shouldn't be 2? why the threshold is from 0.0 to 4.0?
I'm curious about L2 Normalization, which would constrain the embedding into an euclidean feature space and
Thanks!
